Since the discovery of the haloform reaction, 1 the trihalomethyl group has been recognized as a potential leaving group in synthesis and its elimination is usually associated with the development of a negative charge at a β-position. This is the case with the formation of isocyanates after basic treatment of N-monoalkyltrichloroacetamides 2 or in the addition–elimination process between amines and trichloromethylketones. 3 Following our studies on trifluoropyruvamides, 4 we ...
