Directed ortho lithiation of diphenylphosphinic acid and subsequent electrophilic trapping provides mono ortho-functionalized derivatives including enantiopure γ-aminophosphinic acids in moderate yields. Copper catalyzed coupling of the ortho anion leads to biphenyl-2,2′- diylbis(phenylphosphinic acid), a phosphorus analogue of biphenyl-2,2′- dicarboxylic acid. Preliminary studies of the metal-binding abilities of this O,O-chelating ligand towards a series of metal cations are included.

A class of novel phosphorus heterocycles, 1,3-dihydro-2,1-benzoxaphosphole 1-oxides, has been prepared by two different routes.One general approach involves the cyclization of ortho-substituted phenylphosphinic acid derivatives under either thermal or sol
