Direct cross-coupling of aryl alkynyliodines with arylsulfinic acids leading to alkynyl sulfones under catalyst-free conditions
摘要:
A facile and efficient one-pot method has been developed for the construction of alkynyl sulfones via direct cross-coupling reaction of aryl alkynyliodines and arylsulfinic acids. The present transformation could be accomplished under catalyst- and additive-free conditions, providing a series of alkynyl sulfones in moderate to good yields with favorable functional group tolerance.

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.
