Synthesis and Reactivity of a Strongly Pyramidalized P(III)-Compound Embedded into a Pyrrolide (ONO)3– Pincer Ligand

Abstract

A Cs-symmetric P(III) complex bearing a pyrrolide-centered trianionic pincer ligand is reported and its reactivity explored. This compound reacts with alcohols and amines via oxidative addition of their respective O-H and N-H bonds at the P-center, delivering the corresponding P(V) species. DFT calculations, as well as kinetic and isotope labelling analyses suggest the assistance of one of the phenolate side arms in the process.
