Heating of N,N-dimethylformamide azine dihydrochloride N′-[(dimethylamino)methylene]-N,N-dimethylhydrazonoformamide dihydrochloride} with anilines in the absence of a solvent gave a range of 4-aryl-1,2,4-triazoles by direct transamination. Ortho-substituents were tolerated. Some triazoles were converted into symmetrically and nonsymmetrically substituted bistriazolium salts, one of which was converted into a dicopper complex.
在无溶剂的情况下,将 N,N-二甲基甲酰胺偶氮二盐酸盐N′-[(二甲基氨基)亚甲基]-N,N-二甲基肼基甲酰胺二盐酸盐}与苯胺加热,通过直接反式转化得到一系列 4-芳基-1,2,4-三唑。正取代基是可以容忍的。一些三唑被转化为对称和非对称取代的双三唑鎓盐,其中一种被转化为双铜络合物。
