    • For comparison, we have also calculated the energetics of all structures at the BP86 level using the B3LYP geometries (BP86//B3LYP). The calculated energetics (in kcal/mol, without ZPE corrections) are as follows: 1a (0.0), 1b (8.4), 1c (8.8), 1d (3.3), 1e (5.3), 1f (1.0), 1g (9.9), 1h (13.7), 2a (6.3), 2b (10.8), 2c (1.1), 2d (8.3) and 2e (-23.0). Excluding 2e, the two approaches agree to within an average absolute error of 2.0 kcal/mol. However, BP86 predicts the AB of the overall carbonylation reaction (which corresponds to the energy of 2e) to be 9.2 kcal/mol more exoergic than B3LYP. While the experimental value is not known, our earlier study of the carbonylation of pentacarbonyl(methyl)manganese(I) showed very similar behavior. In that case, the experimental value was known, and the calculated value using the B3LYP functional was in much better agreement with experiment. For this reason, we have used the B3LYP energetics as the basis of the mechanistic discussions in what follows.
