Donor-rich and acceptor-rich pyridine-phosphadiazonium adducts: diversifying the Lewis acceptor chemistry of phosphorus(III)

Abstract

[Mes*NP(DMAP)2][OTf] represents the first ligand-rich coordination complex of a phosphorus(III) Lewis acceptor, and a three coordinate hypervalent electron-rich (lone pair bearing) center; further diversification is demonstrated by, [(Mes*NP)2(4,4'-BIPY)][OTf]2, representing an acceptor-rich dication.
