【摘要】 2 氨基噻二唑与芳酰基异氰酸酯反应合成了 13种N -(1, 3, 4 噻二唑- 2基 ) N′ 的芳酰基脲,产率为54. 5% ~86. 2%。用核磁共振氢谱、红外光谱和元素分析确证了目标化合物的结构,室内的生物活性测定试验表明,目标化合物中的 2b、2c、2e和 2h具有优良的植物生长调节活性。更多还原

【Abstract】 Thirteen N-(1,3,4-thiodiazol-2-y1)-N′-aroyl ureas were synthesize d by the reaction of aroyl iso-cyanates with 2-amino-1,3,4-thiodiazole i n yields of 54.5%~86.2%. The structures of the title compounds were confir med by IR, 1H NMR and elemental analysis. The preliminary greenhouse biolo gical activity tests showed that compounds 2b, 2c, 2e and 2h have a good activity in plant growth regulation.更多还原
