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
二乙基-5-甲基-3-氧代-1,2,3,6-四氢-[1,1'-二苯基]-2,6-二羧酸酯与(1-(4-溴苯基)亚乙基)肼的反应是进行,以及该反应产物的晶体结构(二乙基-5-(2-(1-(4-溴苯基)亚乙基)肼基)-3-甲基-1,2-二氢-[1,1'-二苯基]-2,6-二羧酸盐)通过单晶 X 射线衍射测定。环己二烯环的强烈扭曲半椅形式的构象是基于 X 射线衍射数据确定的。注意到 N–H…O=C 型分子内氢键的存在。
