Photodimerization of styrene, p-methylstyrene, and α-methylstyrene in the presence of 1,2,4,5,-tetracyanobenzene
Abstract
U.v. excitation of styrene, p-methylstyrene, and α-methylstyrene in the presence of the electron acceptor tetracyanobenzene produces 1,2,3,4-tetrahydronaphthalene derivatives as the main products in addition to 1,2-cis and 1,2-trans-disubstituted cyclobutanes.
