The product distributions observed after visible light irradiation of a series of 1-alkylcycloalkanols (1-3) and bis(pyridine)iodonium tetrafluo-. roborate (IPy2BF4), have been compared with those observed after irradiation of the same substrates in the presence of (diacetoxy)iodobenzene (DIB) and I-2, i.e. under bona fide conditions for alkoxyl radical generation.

Abstract

The product distributions observed after visible light irradiation of a series of 1-alkylcycloalkanols (1-3) and bis(pyridine)iodonium tetrafluo-. roborate (IPy2BF4), have been compared with those observed after irradiation of the same substrates in the presence of (diacetoxy)iodobenzene (DIB) and I-2, i.e. under bona fide conditions for alkoxyl radical generation. The observation of very similar product distributions with the two systems strongly supports the previous hypothesis that alkoxyl radical intermediates are formed after photolysis of substrates 1-3 in the presence Of IPy2BF4.
