1. Materials and Methods

General Remarks

All preparations and manipulations were carried out under an anhydrous N2 atmosphere using

standard Schlenk and glovebox techniques. All glassware was oven-dried and cooled under

vacuum before use. Commercial available reagents such as SO2Cl2 (1M, CH2Cl2), XeF2,

Et3SiH, Ph2PCl, B(C6F5)3, ketones and aldehydes were purchased from Sigma Aldrich, Strem

or Apollo Scientific and used without further purification unless indicated otherwise.

[Ph3PF][B(C6F5)4] (4),[3] [Et3Si][B(C6F5)4]*2(C7H8),[4] 1,3-dimesityl-4,5-dihydroimidazol-3-

ium-2-ylidene,[4] [(SIMes)PPh2][B(C6F5)4],[6] and [(SIMes)PFPh2][B(C6F5)4]2 (5),[7] were

prepared following procedures described in literature. CH2Cl2, Et2O, n-pentane, and toluene

were dried using an Innovative Technologies solvent purification system. C6H5F and CD2Cl2

(Aldrich) were deoxygenated, distilled over CaH2, then stored over 4 Å molecular sieves

before use. C6D5Br (Aldrich) was deoxygenated and stored over 4 Å molecular sieves before

use. Reactions were monitored using NMR spectroscopy. NMR spectra were obtained on a

Bruker AvanceIII-400 MHz spectrometer, Varian Agilent DD2 500 MHz spectrometer, and

Varian Agilent DD2 600 MHz spectrometer. Data for 1H NMR spectroscopy is reported as

follows: chemical shift (δ ppm), multiplicity (s = singlet, d = doublet, t = triplet, q = quartet,

quin = quintet, m = multiplet, dm = doublet of multiplets, b = broad), coupling constant (Hz),

integration. Data for 13C NMR is reported in terms of chemical shift (δ / ppm). High-

resolution mass spectra (HRMS) were obtained on a micro mass 70S-250 spectrometer (EI),

an ABI/Sciex QStar Mass Spectrometer (DART), or on a JOEL AccuTOF-DART (DART).

Mass spectroscopy experiments were run for isolated products and reaction mixtures, however

in some cases the high fragmentation of compounds or volatility did not allow for mass peak

identification.

X-ray Diffraction Studies.

Single crystals were coated with Paratone-N oil, mounted using a glass fibre pin and frozen in

the cold nitrogen stream of the goniometer. Data sets were collected on a Siemens Smart

System CCD diffractometer which was equipped with a rotation anode using graphite-

monochromated MoKα radiation (λ = 0.71073 Å) Data reduction was performed using the

Bruker SMART[8] software package. Data sets were corrected for absorption effects using

SADABS routine (empirical multi-scan method). Structure solutions were found with the

SHELXS-97 package using the direct method and were refined with SHELXL-97[8] against F2

using first isotropic and anisotropic thermal parameters for all non-hydrogen atoms. Further

details are given in tables in section 4.

2.1. Preparation of [(SIMes)PMe2][B(C6F5)4]

1,3-Dimesityl-4,5-dihydroimidazol-3-ium-2-ylidene (61 mg, 0.2 mmol,

1.0 eq.) was added portionwise to a solution of Me2PCl (20 mg, 0.2 mmol,

1.0 eq.) giving a yellowish solution. The reaction mixture was stirred at

ambient temperature for ten minutes, then freshly prepared

[Et3Si][B(C6F5)4]*2(C7H8) (196 mg, 0.2 mmol, 1.0 eq.) was added. The reaction mixture was

stirred for another ten minutes, then n-pentane (3 mL) was added which led to the formation

of a colorless precipitate. The supernatant was decanted and the residue was washed with n-

pentane (3 x 3 mL). All volatiles were removed in vacuo giving the respective

imidazolidinium-substituted phosphine salt as colorless, microcrystalline solid (96% yield).

3. Catalytic Hydrodeoxygenation of Ketones

3.1. General Procedure for Ketone Hydrosilylation

All reactions were carried out under identical conditions on a 0.1 - 0.2 mmol scale. In a glove

box, the respective catalyst (1 mol%, 1: 2 mg, 7: 2 mg, 6: 2 mg, 8: 2 mg) was added to a

solution of Et3SiH in CD2Cl2 (0.7 mL). The respective substrate (1: 0.16 mmol , 7:

0.11 mmol, 6: 0.11 mmol, 8: 0.11 mmol) was then added in one equivalence. The reaction

mixture was transferred to a NMR tube, sealed and monitored by 1H NMR, 13C NMR and 29Si

NMR. For aromatic ketone 18a once equivalence of Et3SiH and lead to cleanly yield

hydrosilylated product 18b. For most aliphatic ketone substrates the hydrosilylated

intermediates were obtained by using three equivalent of Et3SiH and leaving the reaction at

room temperature for 1 hour. The hydrosilylated product were isolated by removing the

excess silane and solvent under reduced pressure, dissolving in pentane and filtration over a

silica plug. For substrate 25a two equivalence was sufficient to isolate the hydrosilylated

product 25b. For substrate 26a more than one equivalence of silane lead to a mixture of

products, however with one equivalence the hydrosilylated product 26b could be isolated.

3.2. General Procedure for Ketone Hydrodeoxygenation

All reactions were carried out under identical conditions on a 0.1 - 0.2 mmol scale. In a glove

box, the respective catalyst (1 mol%, 1: 2 mg, 7: 2 mg, 6: 2 mg, 8: 2 mg) was added to a

solution of Et3SiH (0.23 – 0.48 mmol, 2.1 – 3.0 eq.) in CD2Cl2 (0.7 mL). The respective

substrate (1: 0.16 mmol , 7: 0.11 mmol, 6: 0.11 mmol, 8: 0.11 mmol) was then added in one

equivalence. The reaction mixture was transferred to a NMR tube, sealed and monitored by

1H NMR and 13C NMR spectroscopy. The bis(triethylsilyl) ether was identified by a 29Si

NMR resonance at 8.88 ppm. In most cases, with 3.1 equivalents Et3SiH, complete

hydrodeoxygenation of ketones was obtained. For examples where the hydrodeoxygenation

product has a low boiling point, an internal standard of toluene was added to determine degree

of conversion. For less volatile products, reaction mixtures were worked-up by evaporating

the di(triethylsilyl) ether by-product. To avoid loss of product under reduced pressure the

solution was occasionally monitored by 1H NMR. For the substrates that could not be isolated,

NMR data for the crude reaction mixture is presented, in which the bis(triethylsilyl) ether by-

product can be observed. Upon completion of catalysis, 31P NMR reveals that the

[C6F5)3PF2] observed in the 31P NMR as a singlet at -8.29 and a triplet -47.99 ppm

consecutively. Routinely, catalytic runs were monitored by 11B and 19F NMR spectroscopy.

According to the NMR data, decomposition of borate anion does not occur for any catalysts

used.

3.10.1 Hydrodeoxygenation of Benzophenone with HSii-Pr3

Catalyst (5) (1 mol%, 2 mg) was dissolved in CD2Cl2 (0.7 mL). Triisopropylsilane (44 µL,

0.76 mmol, 2.1 eq.) was added with a micro-syringe. Benzophenone (20 mg, 0.36 mmol,

1.0 eq.) was added and the reaction mixture was monitored by 1H NMR spectroscopy for

48 h. The analogous reaction with triethylsilane goes to completion within 5 hours.

3.10.2 Reaction of Catalyst 1 with Acetophenone

Catalyst (1) (10 mg) was dissolved in CD2Cl2 (0.7 mL), an excess of acetophenone was

added. The solution was allowed to sit for an hour, before 31P NMR was run. The 1H NMR

revealed a mixture of products and the organic decomposition product could not be identified.

5.1 Calculation Details

The quantum chemical DFT calculations have been performed with the TURBOMOLE 6.4

suite of programs.[24] The structures are fully optimized at the TPSS-D3/def2-TZVP +

COSMO level of theory, which combines the TPSS meta-GGA density functional[25] with the

BJ-damped DFT-D3 dispersion correction[26] and the def2-TZVP basis set,[27] using the

Conductor-like Screening Model (COSMO) continuum solvation model[28] for CH2Cl2 solvent

(dielectric constant = 8.93, refractive constant n = 1.424, Rsolv = 2.94 Å). For the present

(C6F5)3PF+ + O=CPhMe + 2Et3SiH hydrosilylation/deoxygenation reaction system with 92

atoms, it leads to 2064 basis functions (35, 23, 217 atoms and 1091, 319, 2327 basis

functions, respectively) in our DFT calculations. The density-fitting RI-J approach[29] is used

to accelerate the geometry optimization and numerical harmonic frequency calculations in

solution. The optimized structures are characterized by frequency analysis to identify the

nature of located stationary points (no imaginary frequency for true minima and only one

imaginary frequency for transition state) and to provide thermal corrections according to a

modified ideal gasrigid rotorharmonic oscillator model. [30]

The final solvation energies in CH2Cl2 solvent are computed with the COSMO-RS

solvation model (parameter file: BP_TZVP_C30_1201.ctd) in the COSMOtherm program

package[31] on the above TPSS-D3 optimized structures. To check the effects of the chosen

DFT functional on the reaction energies and barriers, gas-phase single-point calculations

using the TPSS-D3, hybrid PW6B95-D3[32] and double-hybrid B2PLYP-D3[33] are performed

using a larger def2-QZVP basis set.[34] It leads to 4545 basis functions (35, 23, 217 atoms

and 2008, 753, 2892 basis functions, respectively) in our single-point calculations. The final

reaction enthalpies (H) and Gibbs free energies (G) are determined from the gas-phase

single-point energies plus thermal corrections plus COSMO-RS solvation energies. The

results from different DFT functionals are in good mutual agreement, especially between the

higher level PW6B95-D3 and B2PLYP-D3 results with a standard deviation of 2.1 kcal/mol.

In our discussion, the final B2PLYP-D3 Gibbs free energies (in kcal/mol, at 298.15 K and 1

atm standard state) will be used unless specified otherwise. The unit cell of

[(SIMes)PMe2F2][B(C6F5)4], [(SIMes)PEt2F2][B(C6F5)4] and

i In order to obtain pure 1,2-bis(4-methoxyphenyl)ethane , it was necessary to leave the reaction mixture under reduced pressure for an extended amount of time. Despite the high molecular weight of the product, these conditions caused significant loss of yield. However the NMR spectra of the reaction mixture shows quantitative conversion to the single 1,2-bis(4-methoxyphenyl)ethane product.
