Abstract

The photochemical reactivity of a series of 4-halobenzonitriles and 4-haloanisoles with 1, 1- diphenylethene in a nucleophilic solvent (methanol) has been investigated. Analysis of the photochemical reactions involving the 4-halobenzonitriles revealed formation of alkene- methanol adducts, such as 1-methoxy-2, 2-diphenylethane, 1-methoxy-2, 2-diphenylethene, and 1, 1-dimethoxy-2, 2-diphenylethane, indicative of a photochemical electron-transfer ...
