Abstract

Abstract The compound 5-chorodibenzophosphole reacts with an equivalent amount or an excess of AI2CI6 in methylene chloride solution to afford the respective tetraorganodiphosphorus cations [R2P (CI) PR2][AICI4](R2= o, o'-dibenzophenylato), 1. However, reaction of t-Bu2PCI with an equivalent amount or an excess of AI2CI6 in CH2CI2 gives rise to a phosphonium ion,[t-Bu2PCI2][AICI4)(2) as the major product, while reaction ...
