Abstract The kinetics of the reaction of 1, 1, 1-trichloro-4-methoxy-3-penten-2-one with various aliphatic and aromatic amines was studied at 25 C in water, dimethyl sulphoxide, methanol, ethanol, chloroform, toluene and hexane. The formation of the corresponding 1, 1, 1-trichloro-4-amino-3-penten-2-one is explained in terms of an addition–elimination mechanism.
