Visible light mediated efficient oxidative benzylic sp3 C–H to ketone derivatives obtained under mild conditions using O2

Author affiliations

Abstract

A photooxygenation of benzylic sp3 C–H reaction has been demonstrated using O2 mediated by visible light. This protocol provides a simple and mild route to obtain ketones from benzylic sp3 C–H bonds. Various benzylic sp3 C–H bonds can be transformed into the desired ketone derivatives in moderate to good yields. The 18O2 labelling experiments demonstrated that the oxygen introduced into ketone originated from dioxygen. A plausible mechanism has been proposed accordingly.
