5-(Methoxy-carbon-yl)thio-phene-2-carboxylic acid.

ABSTRACT: In the title compound, C(7)H(6)O(4)S, a monoester derivative of 2,5-thio-phene-dicarboxylic acid, the carboxylic acid and the carboxylic acid ester groups are approximately coplanar with thio-phene ring, making a dihedral angle of 3.1?(4) and 3.6?(4)°, respectively. In the crystal structure, mol-ecules are connected by classical inter-molecular O-H?O hydrogen bonds, forming centrosymmetric dimers.

Project description:In the title compound, C(12)H(12)O(2)S, the asymmetric unit contains two independent mol-ecules. The chiral C atoms of both mol-ecules were established to be in the R configuration. In both mol-ecules, the 2,5-dihydro-thio-phene rings adopt S-envelope conformations wherein the S atoms are displaced by 0.315?(5) and -0.249?(5)?Å from the mean planes of the remaining ring atoms. In the crystal, the molecules are linked by weak C-H?O interactions.

2-(2,2-Dibromo-ethen-yl)thio-phene.

Project description:The title compound, C(6)H(4)Br(2)S, represents a versatile building block for the preparation of π-conjugated redox-active thienyl oligomers and metal-mediated cross-coupling reactions. This is due to the presence of an electrochemically active thienyl heterocycle and a reactive dibromo-vinyl substituent, which easily undergoes dehydro-bromination in the presence of n-butyl-lithium to afford 2-ethynyl-thio-phene. In the molecule, the alkenyl unit and the thio-phene ring are almost coplanar with an angle of 3.5 (2)° between the normals of the best planes of the thio-phene ring and the vinyl moiety.

2-(9H-Fluoren-9-ylidenemeth-yl)thio-phene.

Project description:The title compound, C(18)H(12)S, contains a thio-phene ring which is disordered by rotation of 180° about the linking C-C bond. The site occupancies of the major and minor components of the disordered ring are 0.900 (3) and 0.100 (3), respectively. In one of these disordered components, the mol-ecule is stabilized by an intra-molecular C-H⋯S hydrogen bond. The compound was synthesized in good yield (80%) by a modified phase-transfer-catalysed condensation of fluorene with thio-phene-2-carbaldehyde.

3-[(2-Formyl-thio-phen-3-yl)(hy-droxy)meth-yl]thio-phene-2-carbaldehyde.

Project description:In the title compound, C(11)H(8)O(3)S(2), the dihedral angle between the mean planes of the two thio-phene rings is 65.10?(10)°. Intra-molecular C-H?O inter-actions form S(6) and S(7) ring motifs. In the crystal, chains along the a axis are formed by C-H?O inter-actions. Adjacent chains are connected into a three-dimensional network by C-H?O and O-H?O inter-actions.
