Ethyl 2-[(Z)-2-benzylhydrazin-1-ylidene]-2-bromoacetate
In the title compound, C(11)H(13)BrN(2)O(2), the dihedral angle between the phenyl ring and the almost planar (r.m.s. deviation = 0.011 Å) C-C(Br)=N-N(H)- fragment is 74.94 (16)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, which generate C(6) chains propagating in [010]. Weak aromatic π-π stacking [centroid-centroid separation = 3.784 (3) Å] may also help to consolidate the ...

The title compound, C(10)H(11)ClN(2)O(2), features an almost planar C(ar)-N(H)-N=C(Cl) unit [torsion angle = 0.8 (1)° whose phenyl substituent is almost coplanar with it [dihedral angle = 2.8 (2)°]; this unit is slightly twisted with respect to the carboxyl -CO(2) fragment [dihedral angle = 10.3 (2)°]. In the crystal, the amino group acts as a hydrogen-bond donor to the carbonyl O atom of an ad...

The title compound, C19H17ClN2O5, is an important inter-mediate for the synthesis of the pesticide Indoxacarb [systematic name: (S)-methyl 7-chloro-2-{[(meth-oxy-carbon-yl)[4-(tri-fluoro-meth-oxy)phen-yl]amino]-carbon-yl}-2H,3H,4aH,5H-indeno-[1,2-e][1,3,4]oxadiazine-4a-carboxyl-ate] The C=N double bond has a Z conformation. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure...
متن کاملSynthesis, tautomeric states and crystal structure of (Z)-ethyl 2-cyano-2-(3H-quinazoline-4-ylidene) acetate and (Z)-ethyl 2-cyano-2-(2-methyl-3H-quinazoline-4-ylidene) acetate.
The new compounds (Z)-ethyl 2-cyano-2-(3H- and 2-methyl-3H-quinazoline-4-ylidene) acetate (1 and 2, respectively) were synthesized by multi-step reactions. The structures in a solution have been determined by (1)H-NMR spectroscopy and in the crystal form by X-ray analysis. Molecule 1 crystallized in a primitive monoclinic cell, space group capital ER, P2(1/c). The cell dimensions are a=7.970(6)...
متن کامل(Z)-Ethyl 2-chloro-2-[2-(4-methylphenyl)hydrazinylidene]acetate
The mol-ecule of the title compound, C11H13ClN2O2, is approximately planar (r.m.s. deviation = 0.099 Å for non-H atoms) and adopts a Z conformation about the C=N double bond. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds to the same O-atom acceptor, forming zigzag chains propagating along [010]. These inter-actions give rise to R2(1)(6) loops.
