Reactions of 1-nitrocyclohexene with N,N-binucleophiles
摘要:
A modification of 1-nitrocyclohexene synthesis is proposed; its reaction with phenylhydrazine and benzoic acid hydrazide is shown to afford monoadducts, and with hydrazine hydrate, bisaduct. With diphenylguanidine occurs heterocyclization to 1-phenyl-2-N-phenylamino-4,5,6,7-tetrahydrobenzimidazole, whose structure is confirmed by the X-ray diffraction data. The analysis performed for this compound of the electron density distribution function in the crystal made it possible to estimate the charge distribution, pi-electrons delocalization nature, and the role of N-H center dot center dot center dot N, C-H center dot center dot center dot H-C and C-H center dot center dot center dot C interactions in the formation of the crystal packing.
