Phosphane-stabilized phosphenium cations react with silanes to effect either reduction to primary or secondary phosphanes, or formation of P-P bonded species depending upon counteranion. This operates for in situ generated phosphenium cations, allowing catalytic reduction of P(III)-Cl bonds in the absence of strong reducing agents. Anion and substituent dependence studies have allowed insight into the competing mechanisms involved.

The reaction of tris(bromo-tert-butylphosphino)phosphane, P(t-BuPBr)3, with lithium aluminium hydride leads to the title compound P(t-BuPH)3 (1), which could be isolated in a pure state. 1 is the first partially substituted derivative of iso-tetraphosphane (6), P(PH2)3, and was characterized in all details.Because of the chirality of the t-BuPH-groups, 1 forms two diastereomers with RRS(SSR)- and RRR(SSS)-configuration in a ratio of about 3:1.The conformation of both isomers, which could be deduced from the 31P NMR parameters, is mainly determined by the steric situation of the molecule. - Keywords: Tris(tert-butylphosphino)phosphane, iso-Tetraphosphanes, Chain Type Organylphosphanes
