Amine-phosphorus halide condensation

Since amine-phosphorus(III) halide condensation reactions are well-established low-energy routes to phosphorus-nitrogen bonds, they provide a logical starting point for examination of skeletally stabilized molecule synthesis. For our initial studies, reactants that are phenyl substituted as opposed to alkyl substituted... 

The hydrohalide is volatilized from the reaction system, driving the condensation to completion. Cyclophosphazanes are formed when tricoordinate phosphorus halides react with amines ... 

Nitrogen, XII, and phosphorus, XIII, analogs to the already described dialkyl-pheriacylsulfonium salts have also been reported to be active photoinitiators for the cationic polymerization of many different types of monomers Their synthesis can be achieved by the direct condensation of phenacyl halides with the appropriate amine or phosphine.
