Abstract

A radical capture mechanism via a synergistic heterogeneous Cu₂O–rGO catalyst for Csp²–H bond immediate hydroxylation has been developed. This protocol suggests the involvement of a C-centered radical (˙C), generated through an O-centered radical (˙OH) initiated hydrogen atom transfer (HAT) process.
