ΔG⧧(300 K) = 14.3 ± 1.8 kcal/mol in toluene-d8 and 15.2 ± 1.9 kcal/mol in CD2Cl2. Thermal decomposition of 7 provides the fourth example of oxygen to metal methyl migration from a methoxycarbyne complex. However, it is the first example in which a methoxycarbyne follows kinetics in which the rate constants are independent of the phosphine concentration, giving k = 8.1 ± 0.6 × 10-5 s-1 at 50 °C in C6D6
