Metal-free thiocyanation of imidazoheterocycles through visible light photoredox catalysis
A visible light mediated, metal-free process for the thiocyanation of imidazoheterocycles has
been developed using eosin Y as a photoredox catalyst under ambient air at room
temperature. A library of 3-(thiocyanato) imidazo [1, 2-a] pyridines with broad functionalities
have been synthesized in high yields. This methodology is also applicable for the
selenocyanation of imidazo [1, 2-a] pyridine.
