Abstract: | Addition of 2-arylaminobenzothiazoles to the C=C bond of methyl acrylate gives a mixture of isomeric 2-arylimino-3-(β-carbomethoxyethyl)benzothiazolines and 2-[N-aryl-N-(β-carbomethoxyethyl)amino]-benzothiazoles. Their thermal stability was studied, HPLC analysis was used to follow the dynamics of the accumulation of the compounds formed in the reaction mixtures.
