The reactions of (η6-arene)Mo(CO)2(Sol) and M(CO)5(Sol) with CO have been studied in a range of alkane solvents (Sol), and the kinetic and activation parameters have been determined (M = Cr, Mo, or W). For M = Cr the ΔH⧧ is constant (22 ± 2 kJ mol-1), while the ΔS⧧ term becomes less negative as the alkane chain length increases. For the larger metals the variation in kinetic and activation parameters
