Methane has been oxidized stoicheiometrically by cobalt(III) trifluoroacetate in CF3CO2H solution at 150-180 deg C and 10-40 atm to give methyl trifluoroacetate in 90 +/- 10percent yield based on COIII, which is reduced to CoII; in the presence of O2 (1-5 atm) the reaction becomes catalytic with respect to the cobalt(III) salt, giving methyl trifluoroacetate as the sole product of the oxidation of methane by dioxygen.

The nature of the protonation reaction of (M = Mo, W; R = Me, Ph, p-MeC6H4) (2) (obtained from (CO)3CpMCH2CCR (1) and Co2(CO)8) to give (3) was further investigated by a crossover experiment.Thus, reaction of an equimolar mixture of 2b (M = W, Cp = η5-C5H5, R = Ph) and 2e ( M = W, Cp = η5-C5H4Me; R = p-MeC6H4) with CF3COOH affords only 3b (same M, Cp, and R as 2b) and 3e (same M, Cp, and R as 2e) to show an intramolecular nature of this transformation.Reaction of (CO)3CpWCH2CCPh (1b) with Co4(CO)12 was also examined and found to yield 2b exclusively.Treatment of 1 with Cp2Mo2(CO)4 at 0-5 deg C provides thermally sensitive compounds, possibly (5), which decompose at room temperature to give Cp2Mo2(CO)6 as the only isolated product.
