Visible light mediated functionalization of allenes

Abstract

Allenes are attractive molecules which serve as versatile synthons for several bioactive compounds and naturally occurring products. In the past few decades, the functionalization of allenes has caught tremendous attention, and several strategies have been developed for the functionalization of allenes. The past decade has witnessed the emergence of visible light mediated photoredox catalysis as a powerful manifold, which has in turn, significantly contributed to the functionalization of allenes via SET- or EnT processes. In this review, the visible light mediated functionalization of allenes has been summarized by compiling the literature of the last 12 years and their reaction mechanisms have been intensively discussed.
