5-Chlorothiophene-2-carboxylic acid is a chlorothiophene derivative with a carboxylic acid functional group attached to the second carbon atom of the thiophene ring.
Physical Properties:
State: Solid
Color: Cream-yellow
Melting Point: 146°C to 150°C
Synthesis:
Method 1:
Start with 2-chlorothiophene.
Add n-butyllithium (n-BuLi) at a temperature of -30°C or lower.
Introduce carbon dioxide to the reaction.
Terminate the reaction and collect the product.
Method 2:
Use lithium diisopropylamide (LDA) as a strong base.
Use anhydrous tetrahydrofuran as a solvent.

Mono and binuclear ruthenium(II) complexes containing 5-chlorothiophene-2-carboxylic acid ligands: Spectroscopic analysis and computational studies

Journal of Molecular Structure Volume 1123, 5 November 2016, Pages 416-425
New Ruthenium complexes I, II and III were synthesized using 5-chlorothiophene-2-carboxylic acid (5TPC), as ligand and the complexes were characterized by elemental analysis, FT-IR, 1H, 13C NMR, and mass spectroscopic techniques. Photophysical and electrochemical studies were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). In the present paper, the selective synthesis and characterization of a 5-chlorothiophene-2-carboxylic acid ligand containing ruthenium mononuclear and binuclear complexes are reported and also carried out the DFT studies.
