Synthesis and Characterization of New Compounds in the Series 1-alkyl-4- [2-aryl-1-diazenyl]piperazines

Abstract

24 New triazenes derived from the 1-alkylpiperazines have been synthesized. Each 1-alkylpiperazine was treated with a diazonium salt solution to produce the new triazenes, which have been characterized by proton and carbon-13 NMR spectroscopy, IR spectroscopy and by mass spectrometric analysis. Assignment of the chemical shifts to specific protons and carbons in the piperazine ring was facilitated by comparison with the chemical shifts in the previously reported 1-methyl-4-[2-aryl-1-diazenyl]piperazines (1).
