1,2-二[4-(2-溴乙氧基)-1-萘氧基]乙烷的结构及其卡宾前体的合成

Structure of 1,2-bis((4-(2-bromoethoxy)naphthalen-1-yl)oxy) ethane and Synthesis of Its Diimidazolium

以1,4-萘醌为原料采用Schlenk技术合成了非预期产物1,2-二[4-(2-溴乙氧基)-1-萘氧基]乙烷,利用1H NMR、13C NMR,尤其是借助DEPT和HSQC谱对其进行了结构确证.该化合物与1-甲基咪唑反应,得到一个新型卡宾前体1,2-双[4-(1-甲基-3-咪唑乙氧基)-1-萘氧基]乙烷六氟合磷酸盐,并利用1H NMR和ESI-MS进行了结构表征,进一步确证了1,2-二[4-(2-溴乙氧基)-1-萘氧基]乙烷的结构.

An unexpected compound 1,2-bis（（4-（2-bromoethoxy）naphthalen-1-yl）oxy）ethane was synthesized by the Schlenk line skill with 1,4-naphthoquinone as starting reactant and its structure was characterized by 1H NMR and 13C NMR based on its DEPT and HSQC spectra.Then the diimidazolium as a novel precursor of N-heterocyclic carbene was synthesized by the title compound with 1-methylimidazole and characterized by 1H NMR and ESI-MS,which further confirmed the title compound structure.
