Thiophene-2-carboxylic acid is an organic compound with the formula SC 4 H 3 CO 2 H. It is one of two mono carboxylic acids of thiophene , the other being thiophene-3-carboxylic acid. [ 1 ] Copper(I) thiophene-2-carboxylate is a catalyst for Ullmann coupling reactions .
Thiophene-2-carboxaldehyde is an organosulfur compound with the formula C 4 H 3 SCHO. It is one of two isomeric thiophenecarboxaldehydes. It is a colorless liquid that often appears amber after storage.
Halogens give initially 2-halo derivatives followed by 2,5-dihalothiophenes; perhalogenation is easily accomplished to give C 4 X 4 S (X = Cl, Br, I). [20] Thiophene brominates 10 7 times faster than does benzene. Acetylation occurs readily to give 2-acetylthiophene, precursor to thiophene-2-carboxylic acid and thiophene-2-acetic acid. [9]
Copper(I) thiophene-2-carboxylate or CuTC is a coordination complex derived from copper and thiophene-2-carboxylic acid. It is used as a reagent to promote the Ullmann reaction between aryl halides. [3] CuTC catalyzed Ullmann coupling
In enzymology, a thiophene-2-carbonyl-CoA monooxygenase (EC 1.14.99.35) is an enzyme that catalyzes the chemical reaction. thiophene-2-carbonyl-CoA + AH 2 + O 2 5-hydroxythiophene-2-carbonyl-CoA + A + H 2 O. The three substrates of this enzyme are thiophene-2-carbonyl-CoA, an electron acceptor AH 2, and O 2.
Thiopropamine is likely to be metabolized into active 4-hydroxymethiopropamine and thiophene S-oxides. [ 3 ] [ 4 ] These are further deaminated by CYP2C in liver transforming them into inactive 1-(Thiophen-2-yl)-2-propan-2-one which is a phenylacetone derivative. [ 5 ]

The Fiesselmann thiophene synthesis is a name reaction in organic chemistry that allows for the generation of 3-hydroxy-2-thiophenecarboxylic acid derivatives from α,β-acetylenic esters with thioglycolic acid and its derivatives under the presence of a base. The reaction was developed by Hans Fiesselmann in the 1950s.
