  The synthesis of tetrazoles is established under metal free conditions at room temperature in the presence of open air. The reaction of 2-bromoaryl isothiocyantes with amines gives thiourea that undergoes reaction in situ with NaN3 using Iodine in the presence of water medium to afford 1-(2-bromophenyl)-N-5-arylaminotetrazoles via substitution followed by electrocyclization processes at ambient temperature

  四唑的合成是在室温、露天存在的无金属条件下进行的。2-溴芳基异硫氰酸酯与胺反应生成硫脲，硫脲在水介质存在下使用碘与 NaN 3 进行原位反应，通过取代得到1- (2-溴苯基)-N -5-芳基氨基四唑，然后在环境温度下进行电环化过程温度。所有给电子和吸电子取代基都很容易发生反应，得到相应的最终产物2a–2ab产量中等至良好。该方法也适用于克级数量的四唑。此外，我们的水性胶束介质表现出良好的可回收活性，并且在最多四个循环中表现出良好的产品收率。
• Copper(I)-Catalyzed Synthesis of Substituted 2-Mercapto Benzimidazoles

  日期：2009.3.6

  An efficient method for the preparation of various substituted 2-mercapto benzimidazoles from their corresponding thioureas has been developed. S-Alkylation of thioureas followed by Cu-catalyzed intramolecular N-arylation furnished substituted 2-mercapto benzimidazoles in high yields and short reaction times. Furthermore, 2-mercapto benzimidazoles substituted with a p-methoxybenzyl group allowed access to benzimidazole thiones.

  Multicomponent reaction: 2‐Azido‐1‐substituted‐1H‐benzo[d]imidazoles were prepared using a copper‐catalyzed three‐component reaction involving 2‐bromoaniline derivatives, isothiocyanates, and sodium azide. The reaction conditions were mild and the scope was broad. The azido compounds were transformed into their 2‐amino and 2‐triazolyl derivatives using copper‐mediated reduction and cycloaddition, respectively
