01 - 177Metal-Assisted Synthesis of New and Highly Functionalized Diphos-phines. — Metal-assisted synthesis of diphosphino ketenimines, derivedfrom one of the simplest and most readily available diphosphine of type (I),is described for complex (III). It is expected to be extended to a numberof cationic bis(diphenylphosphino)methane-manganese complexes bearingtwo-electron ligands other than isocyanide in (I). While the new diphosphineligand (IV) can be isolated from (III) as white microcrystalline solid, it is notpossible so far to isolate the diphosphinoindole ligand from compound (VII).— (RUIZ, J.; RIERA, V.; VIVANCO, M.; LANFRANCHI, M.; TIRIPICCHIO,A.; Organometallics 17 (1998) 18, 3835-3837; Dep.
