摘要

New amphiphilic resin-supported triarylphosphines PEP (1) were designed and prepared on polyethylene glycol-polystyrene graft copolymer (PEG-PS). Palladium complexes of 1, Pd (PEP) 2 (4) and Pd (PEP)(5), catalyzed allylic alkylation of 3-acetoxy-1, 3-diphenyl-1- propene (6) and cinnamyl acetate (7) with various nucleophiles including 1, 3-dicarbonyl compounds, amino acids, sodium azide, and sodium sulfinate, to give quantitative yields ...
