Abstract

Selective mono-deallylation of O, O′-diallylcatechols using 10% Pd/C was investigated to give the correspond-ing allylphenols. A similar reaction of 3-methylene-1, 5- benzodioxepanes afforded O-methacryl catecohols. When substrates bearing various substituents on the benzene ring were subjected to the reaction, regioselective cleavage of an ether bond occurred at the side of para position to an electron-withdrawing group on ...
