Abstract: 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… read more here.

Abstract: A metal-free route to alkynyl sulfones under photoinduced conditions is accomplished, starting from 4-alkyl Hantzsch esters, sulfur dioxide, and alkynyl bromides under visible light irradiation at room temperature. This transformation proceeds smoothly, affording the corresponding… read more here.
