synthesis of 2‐amino‐4‐aryl thiazole derivatives was carried out through the reaction of substituted acetophenones and thiourea using three different types of catalytic systems including N,N,N′,N′‐tetrabromobenzene‐1,3‐disulfonamide [TBBDA], poly(N,N′‐dibromo‐N‐ethylbenzene‐1,3‐disulfonamide) [PBBS] and a combination of TBBDA and nano‐magnetic catalyst supported with functionalized 4‐amino‐pyridine
通过使用三种不同类型的催化系统,包括N,N,N',N'-四溴苯-1,3-,通过取代的苯乙酮与硫脲的反应,进行了2-氨基-4-芳基噻唑衍生物的简单有效合成。二磺酰胺[TBBDA],聚(N,N'-二溴-N-乙基苯-1,3-二磺酰胺)[PBBS]以及TBBDA和纳米磁性催化剂的组合,并由功能化的4-氨基吡啶二氧化硅(MNPs @ SiO 2 -Pr-AP)。结果表明,将TBBDA与MNPs @ SiO 2 -Pr-AP一起使用可在最短的反应时间内获得最高的产品收率。
