Carbonyl ylides as possible intermediates in reactions of a mercurial dichlorocarbene precursor with benzaldehyde
Abstract
The intermediacy of a carbonyl ylide is used to explain why treatment of benzaldehyde with phenyl(bromodichloromethyl)mercury produced phenylmercuric bromide, carbon monoxide, benzal halide, and methyl 2,4-diphenyl-3,5-dioxahexanoate as major products.
