Isomeric 2-amino- and 2-imino-4,4-dialkyl-5-methylenethiazolines give identical methiodides with primary contribution of the imino structure for the anilino derivatives and the amino structure for the alkylamino derivatives. Thermolysis of the salts gives mixtures of thiazolines with amino and imino structures in a ratio of 2∶1.
