Article abstract of DOI:10.1246/cl.1999.49

Highly selective cyclopropanation of ketene silyl acetals with allylic acetates was carried out in the presence of novel η³-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.
