The synthesis, structure and properties of diazaphospholes: Reagents and ligands for asymmetric synthesis

Reaction of C 2 diamines with PCl 3 and Et 3N in toluene, followed by water or hydrogen sulfide, gave a series of cyclic phosphorous acid diamides (diazaphosphole oxides) and thiophosphorous acid diamides (diazaphosphole sulfides), respectively. Similarly, reaction of diamines with phenyl dichlorpho...

Summary:Reaction of C 2 diamines with PCl 3 and Et 3N in toluene, followed by water or hydrogen sulfide, gave a series of cyclic phosphorous acid diamides (diazaphosphole oxides) and thiophosphorous acid diamides (diazaphosphole sulfides), respectively. Similarly, reaction of diamines with phenyl dichlorphosphine gave phenyl diazaphospholes. The synthesis, properties, and structure of these diazaphospholes are reported. Graphic
