A series of substituted diheteroaryl sulfides was synthesized by the reaction of 4,6-diaminopyrimidine-2(1H)-thione with fluoro- and chloroheteroaromatic compounds in the presence of Na2CO3 in acetonitrile under reflux conditions. Our study indicated that 4,6-diaminopyrimidine-2(1H)-thione reacts with fluoro- and chloroheteroaromatic compounds chemoselectively as S- rather than N-nucleophile. The structures
在Na 2 CO 3存在下,在乙腈中,在回流条件下,通过4,6-二氨基嘧啶-2(1 H)-硫酮与氟-和氯杂芳族化合物的反应,合成了一系列取代的二杂芳基硫化物。我们的研究表明,4,6-二氨基嘧啶-2(1 H)-硫酮与氟和氯杂芳族化合物以S-而非N-亲核试剂发生化学选择性反应。合成的化合物的结构通过IR,1 H,19 F和13 C NMR光谱以及元素分析和X射线结构分析得到确认。
