4-Carbonyl-4H-imidazole (10) and 2-carbonyl-2H-imidazole (11) are formed by flash vacuum pyrolysis of methyl 4- and 2-imidazolecarboxylates, respectively. 10 and 11 dimerize to diketopiperazines 14 and 16, respectively.The same products are also obtained from 4- and 2-(anilinocarbonyl)imidazoles, respectively.Methyl imidazole-1-carboxylate (4) on pyrolysis gives a ca. 1:1 mixture of the same ketenes 10 and 11, which dimerizes to a 1:2:1 ratio of diketopiperazines 14-16.In contrast, ethyl imidazole-1-carboxylate gave CO2, ethylene, and imidazole as the major products.The pyrolysis reactions were monitored by low-temperature infrared and high-temperature mass spectrometry.

The imidazole-2-carboxylic acid amides of the general formula STR1 in which R represents alkyl, have powerful growth-regulating properties. The invention provides a method of regulating the growth of plants, which comprises applying to the plants, or to a habitat thereof, a compound of the formula (I) alone or in the form of a composition containing as active ingredient a compound of the formula (I) in admixture with a diluent or carrier.
