摘要
以 2 -氯吡啶为原料,经双氧水和冰醋酸的混合溶液氧化为 2 -氯 N- 氧化物,2- 氯- N- 氧化物经过巯基化、制备钠盐、最后与硫酸锌反应得到吡啶硫酮锌,即 2 -巯基- N- 氧吡啶的锌盐。通过核磁氢谱和质谱对产物的结构进行了表征,并通过系列实验确定了反应的最佳条件。
At first the raw material of title compound, 2-chloropyridine-N-oxide was synthesized using 2-chloropyridine as starting material, acetic acid and hydrogen peroxide as oxidants. Then the final zinc pyridine-2-thiol-N-oxide was obtained starting from 2-chloropyridine-N-oxide via the reactions such as thiolation, preparing sodium salt, reacting with zinc sulfate and so on. And the structure of product was characterized by H NMR and MS. Finally, the optimum reaction conditions were obtained through series experiments.
