The effects of microwave irradiation on the synthesis of (1,2,3-thiadiazol-4-yl)- and (1,2,3-thiadiazol-5-yl)imidazolidine-2,4-diones by cyclocondensation of the respective (1,2,3-thiadiazolyl)ureidoacetic acids were studied. The reactions were studied under the conditions of traditional heating at 140°С temperature and microwave irradiation at 170°С. It was shown that microwave heating of (1,2,3-thiadiazol-5-yl)ureido derivatives of carboxylic acids led to the formation of imidazolidine ring, unlike in the case of (1,2,3-thiadiazol-4yl)ureido derivatives, for which traditional heating was more effective. The derivatives of (1,2,3-thiadiazolyl)imidazolidine-2,4-diones and (1,2,3-thiadiazolyl)ureidoacetic acids were studied with regard to their effects on pine seed germination and seedling growth.
