Formation of phosphanoxy-substituted phosphaalkenes via sterically promoted cleavage of the PP diphosphene bond†
Abstract
The reaction of a kinetically stabilized diphosphene (Mes*PPMes*: Mes* = 2,4,6-tri-tert-butylphenyl) with an organolithium reagent and an acyl halide afforded the corresponding phosphanoxy-substituted phosphaethene [((phosphinidene)methoxy)phosphine] via sterically-promoted bond-cleavage of the P–P bond.
