Visible-light promoted α,α-dibromination in minutes: efficient route for construction of quaternary carbon centers

Visible-light and bromoacetic acid promoted α,α-dibromination was presented in a sustainable manner, which enables the formation of brominated quaternary carbon pre-cursor in minutes. The developed method is well suited for α-heterocyclic carbonyl compounds, which are less issued before. Meanwhile, this method offers the potentiality for stepwise or one-pot construction of quaternary carbon centers.
