[3+2]-Cycloaddition of α-Diazocarbonyl Compounds with Arenediazonium Salts Catalyzed by Silver Nitrate Delivers 2,5-Disubstituted Tetrazoles
硝酸银催化的α-重氮羰基化合物和芳基重氮盐进行[3+2]环加成反应得到2,5-取代的四唑
已经开发了芳族重氮鎓盐与重氮化合物的[3 + 2]-环加成反应（先前仅以三甲基甲硅烷基重氮甲烷和2,2,2-三氟重氮乙烷为例），已包括了多种容易获得的α-重氮羰基化合物。所得的2-芳基-5-酰基-2H-四唑在医学化学中具有很高的价值。
[3+2]-Cycloaddition of arenediazonium salts with diazo compounds (earlier exemplified only for trimethylsilyldiazomethane and 2,2,2-trifluorodiazoethane) has been developed to include a wide range of readily available α-diazocarbonyl compounds. The resulting 2-aryl-5-acyl-2H-tetrazoles are of high value in medicinal chemistry.
