Abstract

Abstract Photochemical electrocyclic reaction mechanism of a variety of heteroatom conjugated systems has been elucidated by a unique concept. The proposed classification of the reaction, which is based upon the number and types of electrons involved in the reaction centers, takes into account the participation of the lone-pair electrons and gives the correct description of the electron behavior during the electrocyclic reaction process.
