Kinetics and thermodynamics of oxidation of some thio acids by tripropylammonium fluorochromate in N, N-dimethyl formamide and acetic acid mixture
Kinetics and mechanism of oxidation of thioglycolic acid (TGA). Thiolactic acid (TLA) and thiomalic acid (TMA) by tripropylammonium fluorochromate (TriPAFC) have been studied in N, N-dimethyl formamide (DMF). The reaction is first order with respect to TriPAFC and thioacids (TA). p-Toluene sulfonic...
