When C-H bond functionalization meets visible-light photoredox catalysis

In recent years, visible-light-mediated C-H bond functionalization has become an emerging field at the forefront of organic synthesis. It is of considerable interest to academic and industrial chemists owing to the atom/step economical features as well as the overall sustainability. In this Letter, we mainly discussed the recent typical examples in sp(2) and sp(3) C-H bond functionalization by means of visible-light photoredox catalysis. (C) 2013 Elsevier Ltd.
