carbene analogues

The electrically neutral mononuclear hydrides of group 14 having two non-bonding

electrons, the electrically neutral mononuclear hydrides of group 15 having four non-bonding electrons, and also the compound HB:. The names of a number of these are

shown below.

RB: boranylidenes RAs: arsanylidenes

RN: nitrenes R2Sn: stannylidenes

R2Si: silylenes RSb: stibanylidenes

RP: phosphanylidenes R2Pb: plumbylidenes

R2Ge: germylidenes

Note that if R = H, these compounds are parent hydrides; derivatives formed bysubstitution are named accordingly. However, if the substituent's first atom, bearing the

free valence, is of the same element as the atom of the carbene analogue, other parent

compounds may be required (see carbenes ), e.g. HN: nitrene; CH3N: methylnitrene;

H2NN: diazanylidene (synonym isodiazene, not aminonitrene ).
