N,N'-二芳基硫代草酰胺与1,2-二溴乙烷的反应的研究

Study on the Reaction of N,N'-Diaryldithiooxamides with 1,2-Dibromoethane

以N,N'-二芳基二硫代草酰胺与1,2-二溴乙烷进行S烷基化反应,合成了一系列2,3-双芳基亚氨基-1,4-二硫杂环己烷,反应在4h内完成,产率52%～62%.产物结构经元素分析,IR,1HNMR及MS表征,并以单晶X射线衍射分析进一步确证.

A series of 2,3-biarylimino-1,4-dithiacyclohexane compounds were synthesized by the sufur-alkylation of N,N'-diaryldithiooxamide with 1,2-dibromoethane in the presence of bases. The reactions were completed in 4 h and the yields were 52%similar to 62%. The structures of the products were established by elemental analysis, IR, H-1 NMR, MS spectra and X-ray diffraction analysis.
