The reaction of chloral with substituted anilines resulted in formation of the respective 2,2,2-trichloroethylidene anilines. Subsequent treatment of these imines in situ with thioglycolic acid produced a series of substituted 2-trichloromethyl-3-phenyl-1,3-thiazolidin-4-ones, This synthetic route was interesting in light of several other possible intermediates which can be formed on reaction of chloral with amines. High resolution (300 MHz) 1H and 13C magnetic resonance spectra and ab initio calculations gave insight into the conformation of the observed products.
