Functional derivatives of thiophene

Chemistry of Heterocyclic Compounds, 1973
A method was developed for the synthesis of 5-acylamino-2,3dimethyl- and 5-acylamino2,3-tetramethyle nethiophenes by decarboxylation of the corresponding 5-acylaminothiop hene4-carboxylie acids. The azo coupling and arninomethylatio n of the synthesized acylaminothiophenes were studied.

Functional thiophene derivatives

Chemistry of Heterocyclic Compounds, 1974
The thiocyanation of 5-acylaminothiophenes gives 4-thiocyanato derivatives, the intramolecular cyclization of which gives 2-acylaminothieno[2,3-d]thiazoles.

Thiophene-Containing Pechmann Dye Derivatives

Organic Letters, 2010
Thiophene-containing Pechmann dyes (unsaturated exo-5,5-dilactones) were easily prepared by Cu-catalyzed dehydration of the corresponding β-aroylacrylic acids. Introduction of long alkyl chains greatly enhances solubility. Isomerization of an alkyl-substituted thiophene Pechmann dye (TPD) gave the corresponding endo-6,6-dilactone.

Plasma Polymerization of Thiophene Derivatives

Langmuir, 2003
To obtain plasma polymerized (PP) layers with a high retention of the conjugated monomer structure, fragmentation during deposition should be minimized. Different methylated and halogenated thiophenes were used as monomers in plasma polymerization, and the influence of the substituent(s) on fragmentation during deposition was investigated.

Synthesis of 2-Thiophene Derivatives

Journal of Pharmaceutical Sciences, 1962
The objective of this present study is the synthesis of certain new 2-thiophene derivatives to be evaluated as potential antispasmodic, analgesic, or local anesthetic agents. The first part of this study concerns the synthesis of β-aminoketones (Mannich bases).

Functional derivatives of thiophene

Chemistry of Heterocyclic Compounds, 1980
We have found that 4-oxothieno[2,3-d]oxazines (lla-h) can be obtained by the action of thionyl chloride on 2-aroylaminothiophene-3-carboxylic acids (la-h) in the presence of dimethylformamide (DMF), i.e., under the conditions of the synthesis of arenecarboxylic acid chlorides.
