Abstract

Electrophilic bromination of alkenes is a fundamental transformation in organic synthesis. The reactions are typically conducted in aqueous base using bromine or N-bromosuccinimide (NBS) as the halogen source. 1 An important research direction is the development of a solid base or acid as a green and recyclable catalyst. Some methods such as SiO 2 /NBS, 2 Tl 2 CO 3 /Br 2 3 and Amberlyst/NBS 4 have been reported. However, recent studies have shown ...
