- 中文摘要: 1-Phenyl-1H-tetrazol-5-ylhydrazine was reacted with nitrous acid to yield 1-phenyl-1H-tetrazolo.lbrak.4,5-d.rbrak.tetrazole. 1-Arylidene-2-(1-phenyl-1H-tetrazol-5-yl)hydrazines (4) were generally reactive towards electrophilic reagents. When treated with bromine in acetic acid, 4 yielded mixtures of 1-arylidene-2-.lbrak.1-(4-bromophenyl)-1H-tetrazol-5-yl.rbrak.hydrazines and 2-.lbrak.1-(4-bromophenyl)-1H-tetrazol-5-yl.rbrak.hydrazidic bromides. Solvolysis of 6a-d in aqueous acetone yielded 5- aryl-1-(4-bromophenyl)-1,2,4-triazolo.lbrak.4,3-d.rbrak.tetrazoles. The structures of the synthesized compounds were confirmed on the basis of elemental analysis, IR and /sup 1/H NMR data.
