三光气在羰基化环合反应中的研究

Research on triphosgene in carbonylation reaction

以三光气为环合试剂、三乙胺为碱,由邻氨基苯酚、邻苯二胺、邻苯二酚分别合成苯并噁唑酮、苯并咪唑酮、1,3苯并二氧戊环2酮。化合物结构经IR、MS和NMR确证。合成方法具有操作简便、所得产品纯度高等特点。

2-Benzoxazolone, 2-benzimidazolone and 1,3-benzodioxol-2-one were synthesized from 2-aminophenol, o-phenylenediamine and catechol, respectively, by using triphosgene and triethylamine. The products were characterized by IR, MS and NMR.The result showed that the method had many advantages, such as easy to operate and high-purity of products.
