Synthesis and Characterization of a Series of 1-Aryl-4-[aryldiazenyl]-
piperazines. Part I. Isomers of N-(2,3-Dimethylphenyl)-N’-(Aryldiazenyl)-
Piperazines
Abstract:This paper describes the synthesis of several new series of 1-(2-aryldiazen-1-yl-) 4-arylpiperazines and 1-(2-aryldiazen-1-yl-)4-arylalkylpiperazines by using diazonium coupling between arenediazonium ions with the appropriate 1-arylpiperazine or the 1-arylalkylpiperazine. The new compounds have a common thread in that they are isomers of the series of N-(2,3-dimethylphenyl)-N'-(aryldiazenyl)-piperazines. The new triazenes have been characterized by IR and NMR spectroscopy and mass spectrometry.
