Abstract
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 of corresponding allylic substituted products in water.
