Photocatalytic alkene reduction by a B12–TiO2 hybrid catalyst coupled with C–F bond cleavage for gem-difluoroolefin synthesis

Abstract

Photocatalytic syntheses of gem-difluoroolefins were performed using the B₁₂–TiO₂ hybrid catalyst during the CC bond reduction of α-trifluoromethyl styrenes with C–F bond cleavage at room temperature under nitrogen. The gem-difluoroolefins were used as synthetic precursors for fluorinated cyclopropanes.
