摘要

Phenyl acetates were selectively obtained in good yields by cyclocarbonylation of 2, 4- pentadienyl acetates in the presence of NEt3, AczO, and a catalytic amount of palladium complexes such as PdClz (PPh3)~ at 120-140 OC under 50 atm of CO. No five-membered ring products were observed. A platinum complex PtClz (PPh3)~ was also effective as a catalyst. The reaction of 5-phenyl-2, 4-pentadienyl bromide with M (CO)(PPh3) 3 (M= Pd ...
