A new and metal-free method has been developed for the synthesis of β-bromo sulfones through the direct difunctionalization of alkenes with sulfinic acids and NBS. This protocol provides a simple, convenient, and efficient approach to various β-bromo sulfones in moderate to good yields with excellent selectivity, and especially does not require any catalyst or additive.
