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°C temperature and microwave irradiation at 170°C. It was shown that microwave heating of (1,2,3-
微波辐射对各自()环缩合反应合成(1,2,3-thiadiazol-4-yl)-和(1,2,3-thiadiazol-5-yl)imidazolidine-2,4-diones的影响研究了1,2,3-噻二唑基)脲基乙酸。在传统的140°C加热和170°C微波辐射的条件下研究了反应。结果表明,与(1,2,3-噻二唑-4-基)不同,微波加热羧酸的(1,2,3-噻二唑-5-基)脲基衍生物导致形成咪唑烷环。 )脲基衍生物,传统加热对其更有效。研究了(1,2,3-噻二唑基)咪唑烷-2,4-二酮和(1,2,3-噻二唑基)脲基乙酸的衍生物对松树种子发芽和幼苗生长的影响。
