(E)-Ethyl 3-(3-bromophenyl)-2-cyanoacrylate
The title mol-ecule, C(12)H(10)BrNO(2), adopts an E configuration with respect to the C=C bond of the acrylate unit. In the crystal structure, mol-ecules are connected by a pair of inter-molecular C-H⋯O hydrogen bonds, forming a centrosymmetric dimer.

In the title compound, C(14)H(16)N(2)O(3)S, the phenyl ring and the ethyl 2-(3-formyl-thio-ureido)acetate fragment adopt an E configuration with respect to the C=C bond. An intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif is observed. In the crystal, mol-ecules are linked by N-H⋯S, C-H⋯S and C-H⋯O hydrogen bonds, forming sheets lying parallel to the ab plane.

6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
متن کاملEthyl (E)-3-anilino-2-cyano-3-mercaptoacrylate
In the title compound, C(12)H(12)N(2)O(2)S, there are S-H⋯N and N-H⋯O hydrogen-bond inter-actions. The N-H⋯O hydrogen bond is bifurcated, with the hydrogen being simultaneously donated to two equivalent O atoms, forming one intra- and one inter-molecular N-H⋯O bond with an R(1) (2)(4) motif. The motif of the S-H⋯N hydrogen bond is R(2) (2)(12).
متن کامل(E)-Ethyl 2-cyano-3-(furan-2-yl)acrylate
There are two independent mol-ecules in the asymmetric unit of the title compound, C(10)H(9)NO(3), in both of which, all non-H atoms except for the methyl C atom lie nearly in the same plane [maximum deviations = 0.094 (3) and 0.043 (2) Å]. In the crystal, each independent mol-ecules is linked by pairs of C-H⋯O inter-actions, generating inversion dimers with R(2) (2)(10) ring motifs.
