Abstract

Geometric isomerizations of alkenes and cyclopropanes have played a key role in the development of mechanistic organic photochemistry.1 Although novel strategies toward obtaining cis geometric isomers have been developed for alkene photoisomerization$_{2} no method is currently available for selective geometric isomerization of trans diarylcyclopropanes. We now present a strategy based on differential cation-ð interaction that has enabled us to selectively convert trans-diphenylcyclopropane (DPC) to the corresponding cis isomer.
