Graphene oxide (GO) has been found to be highly efficient and recyclable carbocatalyst for the benign construction of heterocyclic molecule 1,4-benzothiazine from 2-aminothiophenol and 1,3-dicarbonyl compound. A vast range of highly functionalized 1,4-benzothiazine derivatives has been synthesized constituting a general and sustainable protocol. It is proposed that the large surface area of GO nanosheet
已经发现氧化石墨烯(GO)是用于由2-氨基硫酚和1,3-二羰基化合物良性构建杂环分子1,4-苯并噻嗪的高效且可回收的碳催化剂。合成了广泛的高度官能化的1,4-苯并噻嗪衍生物,构成了一般且可持续的方案。提出GO纳米片的大表面积以及在边缘,基面和插入层上存在的酸性和氧化基团的存在有效地催化了氧化环化。
