(E)-Methyl N′-[1-(4-methoxyphenyl)ethylidene]hydrazinecarboxylate

Abstract

Key indicators: single-crystal X-ray study; T = 273 K; mean (C-C) = 0.002 Å; R factor = 0.037; wR factor = 0.102; data-to-parameter ratio = 12.8.The molecule of the title compound, C 11 H 14 N 2 O 3 , adopts a trans configuration with respect to the C N bond. The dihedral angle between the benzene ring and the hydrazinecarboxylate plane is 12.06 (9) . Molecules are linked into a one-dimensional network by N-HÁ Á ÁO hydrogen bonds and C-HÁ Á Á interactions. The benzene rings of inversion-related molecules are stacked with their centroids separated by 3.777 (1) Å , indicating -interactions. Related literature

“…11 When preparing 2a-g from 1a-g, the literature method was modified by using Cl 2 as a chlorinating agent instead of using SOCl 2 . 12 2-Methoxy-5-phenyl-1,3,4-oxadiazole (4) was synthesised by the intramolecular cyclisation reaction of 2a in benzene, a solvent of low polarity.…”
