An original and efficient copper-catalyzed 1,6-hydrodifluoroacetylation of para-quinone methides with difluoroalkyl bromides has been described with bis(pinacolato)diboron (B2pin2) as reductant. In this reaction, a new C(sp3)-CF2 bond is constructed under smart conditions. A broad substrate scope of para-quinone methides (p-QMs) make this protocol very practical and attractive. Preliminary mechanistic studies manifested that a difluoroalkyl radical pathway was involved in this reaction. Also the presence of the diboron reagent was an essential requisite in this transformation.
