                                    Ethyl 4,4,4-trifluorocrotonate I readily adds aliphatic and aromatic thiols and aminothiols at the double bond in the presence of catalytic amounts of alkylamines and ammonia to give 3-thiolation products. Thiolacetic acid reacts with ester I in the absence of a catalyst at 100degreesC.
