Abstract
The reaction of diethyl-5-methyl-3-oxo-1,2,3,6-tetrahydro-[1,1¢-diphenyl]-2,6-dicarboxylate with (1-(4-bromophenyl)ethylidene)hydrazine is conducted, and the crystal structure of the product of this reaction (diethyl-5-(2-(1-(4-bromophenyl)ethylidene)hydrazinyl)-3-methyl-1,2-dihydro-[1,1¢-diphenyl]-2,6-dicarboxylate) is determined by single crystal X-ray diffraction. The conformation of the cyclohexadiene ring in the form of a strongly distorted half-chair is determined based on the X-ray diffraction data. The presence of the intramolecular hydrogen bond of the N-Н…О=C type is noted.
