Abstract

Abstract:

Intramolecuar photocyclodehydrogenation of hexa(4-substituted-phenyl)benzene was studied. The photocyclodehydrogenation reaction gives the only product with one bond formation, which is different from the steady state cyclodehydrogenation reaction. The yield of photocyclodehydrogenation product was affected by the amount and the type of oxidants, and solvents. The yield of 91% has been achieved in n-hexane by using iodine as the oxidant.

Key words: hexa(4-substituted-phenyl)benzene, photocyclodehydrogenation reaction, oxidation
