PHOTOCHEMICAL REACTIONS OF α-METHYLSTYRENE INDUCED By Eu(III)/Eu(II) PHOTOREDOX SYSTEM IN METHANOL

Photoirradiation of a methanol solution of α-methylstyrene and EUCl3·6H2O with Pyrex filter resulted in the formation of 2,3-dimethyl-2,3-diphenylbutane and 3,4-dimethyl-3,4-diphenylpentanol in high yields. This reaction was initiated By the excitation of Eu(III)–CH3OH CT-bands and followed By a successive photochemical reaction of Eu(II) ions formed.
