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

Article abstract of DOI:10.1246/cl.1985.893

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.
