水溶液常温条件下制备咪唑啉硫酮类杂环化合物

摘要

Using ethylenediamine and carbon disulfide as raw materials,2-imidazolinethione was prepared in water at room temperature.The effects of preparation conditions and different substrates on reaction were in-vestigated.The products were characterized by melting point,1 HNMR,IR and MS.Results showed that,1,2-cy-clohexanediamine,o-phenylenediamine,o-aminophenol,1,6-hexanediamine and naphthyl ethylenediamine dihy-drochloride were applicable to the method to give the desired products.%在水相中以乙二胺和二硫化碳常温反应制备2-咪唑啉硫酮，对制备条件进行了优化，探讨了不同底物对反应的影响，并通过熔点、核磁共振氢谱、红外光谱、质谱对产物进行了表征。结果表明，1，2-环己二胺、邻苯二胺、邻氨基苯酚、1，6-己二胺、盐酸萘乙二胺等底物均能适用于本反应而得到预期的产物。
