Title
Involvement of alkoxyl radical intermediates in the photolysis of 1-alkylcycloalkanols in the presence of bis(pyridine)iodonium tetrafluoroborate: Comparison with the (diacetoxyiodo)benzene/I2 system
Abstract

The product distributions observed after visible light irradiation of a series of 1-alkylcycloalkanols (1–3) and bis(pyridine)iodonium tetrafluoroborate (IPy2BF4), have been compared with those observed after irradiation of the same substrates in the presence of (diacetoxy)iodobenzene (DIB) and I2, 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.
