Flash photolysis studies on Mn2(CO)10 in cyclohexane and THF show that the dominant photochemistry involves photolytic formation of 2 Mn(CO)5 followed by recombination at rates near the diffusion-controlled limit. A second, relatively, long-lived intermediate is also observed and earlier observations of photodecomposition and photodisproportionation can be accounted for in terms of secondary photolysis of this intermediate. For the equilibrium: Mn2(CO)10 ⇌ 2 Mn(CO)5 △H ∼ 36 kcal/mol, △S ∼ 32 e.u., and K(25°C) ∼ 10-20 where the thermodynamic values have been estimated from kinetic measurements. 1977.
