Reactions of Silicon-Silicon Bonds, VI. Reductive Trichlorosilylation Reactions Leading to Alkyl- and Dialkylaminobis(trichlorosilyl)phosphanes
Reactions of hexachlorodisilane and of trichlorosilane/triethylamine with alkyl- and dialkylaminodichlorophosphanes RPCl2 1a-f furnish bis(trichlorosilyl)phosphanes RP(SiCl3)2 3a-f.However, when less bulky substituents are attached to the phosphorus atom, so that there is little steric crowding, the double reductive silylations leading from 1 to 3 are accompanied by side reactions and decomposition of 3.Therefore, only 3b, 3c, 3d and 3f were isolated in a pure state.These compounds are more readily prepared by the trichlorosilane/triethylamine method. 1H-, 31P- and 29Si-NMR spectra confirm their constitution.The structure of solid 3f, the first aminobis(trichlorosilyl)phosphane, was determined by X-ray crystallography. 3f contains a phosphorus atom in a pyramidal environment surrounded by two silicon atoms and a planar nitrogen atom of the diisopropylamino group. - Keywords: Trichlorosilylation; Dichlorophosphanes; Silylphosphanes; Amino(silyl)phosphanes; Silicon; Reductions

ZUR KENNTNIS DER ORGANOPHOSPHORVERBINDUNGEN, XXI. Darstellung von Organobromphosphanen aus RPCl2 und R2PCl durch Halogenaustausch.
Several methods for the preparation of organobromophosphanes from RPCl2 and R2PCl by halogen exchange are described.In case of aryl compounds optimal results are obtained by equilibration of the chlorophosphanes with PBr3 followed by distillation or cryst
