Reactions of a dinuclear chloro-bridged cyclopalladated complex (CPC) derived from N,N-dimethylbenzylamine with HPPh2under a variety of conditions resulted in the phosphination of the cyclopalladated ligand. The best yield (77%) of the reaction product, ortho-(diphenylphosphino)-N,N-dimethylbenzylamine, was achieved using 4.5 equiv. of HPPh2in toluene in the presence of Cs2CO3at 40?°C. The scope of the reaction was explored with a range of enantiopure and achiral C,N, C,S and C,P CPCs having either five- or six-membered rings and containing either an sp2or sp3C[sbnd]Pd bond. The corresponding N,P, S,P, and P,P ligands or their oxides were isolated in 30–70% yields. Reactions of HPPh2in toluene with CPCs derived from D-camphor methyloxime and 2-tert-butyl-4,4-dimethyl-2-oxazoline provided unique mononuclear Pd(II) complexes with a terminal PPh2ligand in 16 and 52% yield, respectively. Structures of all new compounds were supported by1H,13C{1H}, DEPT,31P{1H}, and 2D NMR spectra.

Readily available air- and moisture-stable dimeric chloro-bridged CN-, CS- and CP-cyclopalladated complexes with the (sp2)C-Pd bond react with 4.5 equiv. of KPPh2 in THF to give the corresponding P,N-, P,S- and P,P-bidentate ligands
