Vanadium-catalyzed carboxylation of linear and cyclic C5 and C6 alkanes

Cyclopentane, cyclohexane, pentane, and hexane are carbonylated in single-pot processes and under mild conditions to carboxylic acids (highest yields of 54-33% and turnover numbers [TONs] of 76-50) by vanadium (IV) and (V) complexes in TFA. These complexes present N,O- or O,O-ligands, namely basic forms of aminoalcohols and of (hydroxyimino)dicarboxylic acids, trifluoroacetate, or triflate. The effects of various parameters (e.g., catalyst type, oxidizing agent, CO pressure, temperature, reaction time, type of solvent) were investigated. The use of either too low or too high CO pressures is discouraged, because the former promote the formation of trifluoroacetate esters and the latter, above a certain level, do not result in higher yields or TONs of the carboxylic acids. Carbon- and oxygen-centered radical mechanisms are suggested by experiments with radical traps and by acid product distribution.

Cobalt catalyzed carboxylation reaction of saturated hydrocarbons with CO in the presence of K2S2O8 and TFA under mild conditions

Cobalt(II) acetate (Co(OAc)2) has been found to be an efficient catalyst for the carboxylation reaction of saturated hydrocarbons with CO to yield the corresponding carboxylic acids in high yields in the presence of K2S2O8 and CF3COOH. About 89.5% conversion of propane is obtained in this reaction. The activation parameters of the reaction of propane have been determined by Arrhenius and Eyring plots.
