Abstract
In a useful synthesis of phenols from arylboronic acids, hydrogen peroxide is generated in situ by aerobic photooxidation using visible-light irradiation and easily handled 2-chloroanthraquinone as an organocatalyst. The mild, metal- and base-free conditions enable an environmentally benign approach to the synthesis of phenols from arylboronic acids.
