Abstract
Abstract The cyclopropanation of alkenes, dienes and trienes with ethyl diazoacetate catalyzed by tris(4-bromophenyl)aminium hexachloroantimonate have been studied. The efficiency and selectivity of cyclopropanation is based solely upon, and is highly sensitive to, the ease of ionization of π bonds in the substrate. Simple double bonds such as norbornene and 1-octene are not amenable to cyclopropanation via this method.
