Abstract

The kinetics of the reaction of (+)-3-methyl cyclohexanone with malononitrile were studied in benzene at 25°, in the presence of hexylamine-acetic acid mixtures. Hexylamine gives an imine with cyclohexanone in an acid-catalysed step. This imine then reacts quickly with malononitrile. A rate law of zero order in malononitrile is observed. Separate kinetic results obtained for the formation of the imine and for the imine-malonitrile reaction support this ...
