Three series of new 1-(isomeric methyl)benzoyl-3-arylthioureas (1–3a–i) were prepared from 2-, 3-, and 4-methylbenzoyl chlorides via isothiocyanate formation followed by treatment with various substituted anilines. The base-catalyzed condensation of thioureas (1–3a–i) with acetone was carried out in the presence of bromine to afford the corresponding 1-(isomeric methyl) benzoyl-3-aryl-4-methyl-imidazole-2-thiones
由2-,3-和4-甲基苯甲酰氯经异硫氰酸酯形成,然后用各种取代的苯胺处理,制备了三组新的1-(异构甲基)苯甲酰基-3-芳基 硫脲(1-3a-i) 。在溴存在下,进行硫脲 (1-3a-i) 与丙酮的碱催化缩合 反应,得到相应的1-(异构甲基)苯甲酰基-3-苯甲酰基-3-芳基-4-甲基咪唑-2-硫酮 ( 4–6a–i) 产量高。硫脲和相应的硫酮通过光谱数据和元素分析进行表征。还讨论了硫酮的质量裂解模式。评价了该硫酮的抗菌,抗真菌和杀虫活性,并显示出显着的抗菌活性和轻微但不显着的抗真菌和杀虫特性。
