Abstract;Highly selective cyclopropanation of ketene silyl acetals with allylic acetates was carried out in the presence of novel .ETA.3-allylpalladium-pyridinylimidazole complexes and sodium acetate in DMSO at room temperature. When cinnamyl acetate was used as an allylic acetate, phenylcyclopropane derivative was obtained stereoselectively in 83% yield. (author abst.)
