Synthesis and transformations of 3-aryl-5-dichloromethyl-1H-1,2,4-triazoles
摘要:
A method of synthesis of 3-aryl-5-dichloromethyl-1H-1,2,4-triazoles was developed, some chemical transformations of the synthesized compounds were performed, and dichloromethyl fragment in these compounds was shown to exhibit the characteristics of aldehyde group.

Easily accessible 1-aryl-2-aza-1,3-butadienes undergo a regioselective cyclocondensation with 2-(aminomethyl)aniline, giving rise to 1,3,5-benzotriazocines in good yields. The structure of the title compounds was proved with the aid of H-1 and C-13 NMR spectra and, in one case, single-crystal x-ray analysis. [Supplementary materials are available for this article.
