As. Morkovnik et Vn. Khrustalev, ON PRODUCTS OF REACTION OF IMIDAZOLE WITH BENZOYL CHLORIDE UNDER CONDITIONS OF THE REGEL-BUCHEL REACTION, Russian chemical bulletin, 47(8), 1998, pp. 1550-1552
The reaction of imidazole with benzoyl chloride in pyridine afforded c
is-1,2-bis(benzoylamino)ethylene (1) rather than 2-benzoylimidazole, a
s has been suggested previously. The structure of 1 was confirmed by H
-1 NMR spectroscopy and X-ray diffraction study.
