An electrophotochemical ring-opening bromination of unstrainedtert-cycloalkanols has been developed. This electrophotochemical method enables the oxidative transformation of cycloalkanols with 5- to 7-membered rings into synthetically useful ω-bromoketones without the use of chemical oxidants or transition-metal catalysts. Alkoxy radical species would be key intermediates in the present transformation, which generate through homolysis of the O-Br bond in hypobromite intermediates under visible light irradiation.

Alcohols were found to be arylated directly at their α-C?H bond with aryl halides in the presence of a base and a substoichiometric amount of t-BuOOt-Bu through a homolytic aromatic substitution mechanism. (Figure presented.).
