  一种制备质子化-NHCs及相关化合物的新合成方法

  摘要：

  N-杂环卡宾 (NHC,H + ) 的质子化形式通常通过引入 CH +片段闭合环来制备。在这里，我们报告了一种完全不同的合成方法，可以将其视为将 1,3-二氮杂烯丙基阴离子添加到具有两个离去基团的化合物（以下称为“亲电试剂”）中。使用 1,3- 和 1,4- 二溴化物、六元和七元 NHC,H +s 已准备好收率。类似地，以 1,3,2-dioxathiolane-2,2-dioxide 作为二亲电子试剂，获得咪唑啉盐。为了说明其广泛的应用范围，该合成路线已扩展到分别使用 1-氮杂-烯丙基和 1,3-硫代-烯丙基阴离子制备质子化环状氨基烷基卡宾 (CAAC) 和氨基硫代卡宾。

  Protonated versions of N-heterocyclic carbenes (NHC,H+) are classically prepared by closing the ring through the introduction of the CH+ fragment. Here we report a totally different synthetic approach, which can be viewed as the addition of a 1,3-diazaallyl anion to a compound featuring two leaving groups (hereafter named “di-electrophile”). Using 1,3- and 1,4-dibromides, six- and seven-membered NHC

  N-杂环卡宾 (NHC,H + ) 的质子化形式通常通过引入 CH +片段闭合环来制备。在这里，我们报告了一种完全不同的合成方法，可以将其视为将 1,3-二氮杂烯丙基阴离子添加到具有两个离去基团的化合物（以下称为“亲电试剂”）中。使用 1,3- 和 1,4- 二溴化物、六元和七元 NHC,H +s 已准备好收率。类似地，以 1,3,2-dioxathiolane-2,2-dioxide 作为二亲电子试剂，获得咪唑啉盐。为了说明其广泛的应用范围，该合成路线已扩展到分别使用 1-氮杂-烯丙基和 1,3-硫代-烯丙基阴离子制备质子化环状氨基烷基卡宾 (CAAC) 和氨基硫代卡宾。
