A facile synthesis of imidazoles and tetrazoles via [3+1+1] type cyclization of ClCF2COONa is developed. A diverse array of imidazoles and tetrazoles were obtained in decent yields via isocyanide intermediates. Notably, this is the first example of the cycloaddition of in situ generated isocyanides.

A novel and green Co@g-C3N4 catalyzed visible light driven direct regioselective synthesis of 1H-tetrazoles directly from various aldehydes and sodium azide is reported. Herein, NaN3 not only behaves as a three-nitrogen donor of the tetrazole ring but also it converts aldehyde into isocyanide as a one-nitrogen source. The regioselectivity of the product, operational simplicity, ambient reaction conditions
报道了新颖的和绿色的Co @ gC 3 N 4催化可见光驱动的直接由各种醛和叠氮化钠直接区域选择性合成1 H-四唑。在此,NaN 3不仅起到四唑环的三氮供体的作用,而且还将醛转化成作为一氮源的异氰酸酯。产品的区域选择性,操作简便,环境反应条件,不使用柱色谱法进行纯化,优异的产品收率(84–95%)和催化剂的可回收性高达五倍,而形态和催化效率没有任何实质性变化是所设想协议的显着特征。

methods are aimed at carrying out reactions under more efficient conditions and the realization of the twelve principles of green chemistry. Due to the importance and widespread applications of tetrazoles in various industries, especially in the field of pharmaceutical chemistry, and the expansion of the use of nanocatalysts in the preparation of valuable chemical reaction products, we decided to use an
