Abstract
Two novel biphenyls, 2,2′-bis(1-hydroxyethyl)-3,3′,5,5′-tetramethylbiphenyl (7) and 2,2′-bis(1-hydroxyethyl)-4,4′,6,6′-tetramethylbiphenyl (13) were synthesized through Wittig reaction, photochemical oxidative cyclization, and ozonolysis, using xylene and mesitylene as starting materials. The novel approach is applicable to both symmetrical and unsymmetrical biphenyls.Keywords
