Abstract
Herein, we report a visible-light-induced iridium-promoted direct bifunctionalization of 3-butenoic acid with bromodifluoromethyl heteroarylsulfones. This methodology enables the concurrent introduction of difluoromethyl heteroarylsulfone and bromine groups into 3-butenoic acid under mild reaction conditions. Various α-substituted 3-butenoic acids and bromodifluoromethyl heteroarylsulfones were found to be compatible, yielding the corresponding products in moderate to good yields. This method opens a new route for the synthesis of fluorocarboxylic acid derivatives.
