Abstract
New amphiphilic resin-supported triarylphosphines PEP (1) were designed and prepared on polyethylene glycol-polystyrene graft copolymer (PEG-PS). Pall adium complexes of 1, Pd(PEP)(2) (4) and Pd(PEP) (5), catalyzed allylic alk ylation of 3-acetoxy-1,3-diphenyl-1-propene (6) and cinnamyl acetate (7) wi th various nucleophiles including 1,3-dicarbonyl compounds, amino acids, so dium azide, and sodium sulfinate, to give quantitative yields of correspond ing allylic substituted products in water.
