Photooxidation of mixed aryl and biarylphosphines

Arylphosphines and dialkylbiarylphosphines react with singlet oxygen to form phosphine oxides and phosphinate esters. For mixed arylphosphines, the most electron-rich aryl group migrates to form the phosphinate, while for dialkylbiarylphosphines migration of the alkyl group occurs. Dialkylbiarylphosphines also yield arene epoxides, especially in electron-rich systems. Phosphinate ester formation is increased at high temperature, while protic solvents increase the yield of epoxide. The product distribution provides evidence for Buchwalds recent conformational model for the aerobic oxidation of dialkylbiarylphosphines.

Preparation of N-phenyl-(S)-prolinol-derived P,N-ligands and their application in Pd-catalyzed asymmetric allylic alkylation

Several NPN-type ligands bearing two chiral pyrrolidinyl groups derived from N-phenyl-(S)-prolinol were prepared by two synthetic methods. Their palladium-complex-catalyzed asymmetric allylic alkylation of malonates with 1,3-diphenyl 2-propenyl acetate delivered the products with good to high enantioselectivities (84-97% ee), including an optically active fluorine-containing compound.
