Photocatalysed eosin Y mediated C(sp3)-H alkylation of amine substrates via direct HAT

Abstract A visible light promoted, photoredox catalysed, green one-pot approach for the alkylation of amine substrates with sp 2 carbon has been developed. This eosin Y based organic transformations, can behave as an effective direct hydrogen-atom transfer catalyst for coupling reaction. The proposed strategy includes simple procedure which can make adduct product with sp 2 carbon. This eosin Y based photocatalytic hydrogen-atom transfer strategy may hold great potential for diverse functionalization of a wide range of native C H bonds in an economical and sustainable manner.
