Abstract
Diethyl 2,2'-[biphenyl-4,4'-diyldihydrazin-2-yl-1-ylidene]bis(chloroacetate) was synthesized in high yield via Japp–Klingemann reaction. The structure of this compound was fully characterized by IR, 1H-NMR, 13C-NMR, Mass spectra and elemental analysis.
Highlights
Bis-hydrazonoyl chlorides are highly versatile and useful building blocks for the synthesis of a wide variety of bis-heterocycles [1,2,3,4]
In continuation of our research work concerned with the synthesis of novel hydrazonoyl halides and their use in the preparation of polysubstituted heterocycles [2], we report a convenient route to diethyl
The bis-hydrazonoyl chloride 3 was prepared by coupling of benzidine diazonium chloride 2 with
