In organic chemistry, thiocarboxylic acids are organosulfur compounds related to carboxylic acids by replacement of one of the oxygen atoms with a sulfur atom. Two tautomers are possible: a thione form (RC(S)OH) and a thiol form (RC(O)SH). These are sometimes also referred to as "carbothioic O-acid" and … See more Thiocarboxylic acids are typically prepared by salt metathesis from the acid chloride, as in the following conversion of benzoyl chloride to thiobenzoic acid using potassium hydrosulfide according to the following idealized equation: See more Dithiocarboxylic acids, with the formula RCS2H, are less common than the monothio derivatives. They are about 3x more acidic than the monothiocarboxylic acids. Thus, for dithiobenzoic acid pKa = 1.92. Such compounds are commonly prepared by the … See more At neutral pH, thiocarboxylic acids are fully ionized. Thiocarboxylic acids are about 100 times more acidic than the analogous carboxylic acids. For PhC(O)SH pKa = 2.48 vs 4.20 for PhC(O)OH. For thioacetic acid the pKa is near 3.4 vs 4.72 for acetic acid See more • Thioester • Thiocarbamate • Thiocarbonate • Thiocarbonic acid See more WebThe enforcement of low coordination numbers can be achieved by having a ligand with large steric demand. The terphenyl-based ligand frameworks, Fig. 2, can provide such steric properties.Several derivatives of terphenyl ligands with nearly every main group element have been synthesized. 9 Our interest was to use dithiocarboxylate, thiolate, and …

WebUsing nonequilibrium Green’s function and first-principles calculations, we investigate the effects of different molecular conformations induced by torsion angle on electronic transport and their stability in 4,4′-biphenyl bis (dithiocarboxylate) molecular junction under an applied electric field. The results indicate that there are two stable conformations existed … WebThe article was published on 2024-02-01. It has received 7 citation(s) till now.
