Regioselective synthesis of α-fluoro-β-arylalkenyl sulfides has been established withgem-difluoroalkenes and sodium sulfinates in a transition-metal-free manner. A series of control experiments were executed to demonstrate thiol radicals and anions as the proposed intermediates. Notably, regioselectiveZ→Eisomerization was achieved under green light irradiation in the absence of a photoinitiator.

A facile and efficient method for the synthesis of (E/Z)-α-fluorovinyl phosphorus compounds from gem-difluorostyrenes with diphenylphosphine oxide/dialkyl phosphate and DBU at room temperature was developed. A series of 1-fluorovinyl phosphine oxides/phosphonates were obtained with moderate to excellent yields in these reactions. Additionally, most isomers (E/Z type) of the target compounds could be easily separated and purified by column chromatography.
Nucleophilic difluoromethylation of aromatic aldehydes using trimethyl(trifluoromethyl)silane (TMSCF3)
