Abstract
A formal
Cu-catalyzed C(sp<sup>2</sup>)–H hydroxylation
assisted by benzoic acids is described. The procedure is characterized
by its mild reaction conditions and wide substrate scope utilizing
simple and cheap Cu catalysts, thus becoming a user-friendly and operationally
simple protocol for C(sp<sup>2</sup>)–H hydroxylation
