Synthesis and Structure of an Imino(phosphoranylidenemethyl)phosphine: A New Hetero Allyl Anion Reaction of the (dichlorophosphinyl)methylphosphonium salt 1 with three equivalents of sodium bis(trimethylsilyl)amide ( 2 ) in THF at – 78°C leads to the P ‐(phosphoranylidenemethyl)‐substituted iminophosphine 4 . Compound 4 is probably formed via 3 by 1,3‐silyl migration. According to an X‐ray analysis, 4 can be described as a hetero allyl anion with a 3‐ center‐4‐electron bond C1–P1–N1. Oxidative addition of sulfur or selenium results in formation of the imino(thioxo)phosphorane 8 or imino(selenoxo)phosphorane 9 .
