1,1-Bis(dimethylamino)-2,2-difluoroethene has been shown to be a diverse and highly effective building block for the preparation of a variety of fluorinated compounds. Reported here are preliminary results of its use for acylation reactions with acyl chlorides to form 2,2-difluoroketoacetamides as well as for its direct condensation with various acidic α-hydrogen carbon compounds to form a variety of functionalized difluoromethyl enamines.
