Ethylaluminum as an ethylene source for the Mizoroki–Heck-type reaction. Rhodium-catalyzed preparation of stilbene derivatives†
Abstract
Treatment of an organoaluminum reagent bearing aryl and ethyl groups furnishes 1,2-diarylethene derivatives in good to excellent yields by the catalysis of a rhodium complex, in which the ethyl group of the aluminum reagent serves as an ethylene source in the product formation.
