A general and simple protocol for the synthesis of α-substituted alkenylsulfones has been developed firstly via palladium-catalyzed Suzuki reactions between α-bromo ethenylsulfones and organoborons. Using a catalyst composed of Pd(OAc)2 and SPhos, a variety of aryl, heteroaryl, and alkylboron reagents could efficiently couple with α-bromo ethenylsulfones under mild conditions. Moreover, it has been

(Het)Arylallenes undergo hydrosulfonylation under photoredox-catalyzed conditions. The reaction gives vinyl sulfones in a regio- and diastereoselective manner, employing sodium sulfinates as the sulfonyl source and eosin Y as the photocatalyst. Indol-1-yl, pyrrol-1-yl, phenyl, and naphtylallenes might be used. Aliphatic allenes are incompatible with the reaction conditions.
