Abstract
The photolysis of several alkanophenones in monovalent cation exchanged faujasites and in pentasil zeolites, occured with expected γ-hydrogen abstraction and the ratio of the products derived differed; cyclobutanol formation was completely suppressed in pentasils, probably due to restruction of the rotational motion of the central σ bond present in the Norrish type II derived 1,4-diradical.Keywords
