The stereoselectivity of the anodic acetoxylation of double bonds. The reactivity of 2,3-diphenylindenone
Abstract
When the anodic addition of 2,3-diphenylindenone is conducted in acetic acid, the predominance of the cis-isomer may be explained by the formation of an acetoxonium ion intermediate; this assumption is verified by isolation in high yield of themethoxylated form of this intermediate under particular conditions, and its structure has been determined by X-ray crystallography.
