Example text

Indeed, the barrier observed for the reaction, CoCH2++CH4ÆCo++C2H6, is measured as 27±10 kJ mol–1, while that for the analogous reaction (11) is 54±8 kJ mol–1. One difference between the two systems is that the former reaction is spin-allowed, while reaction (11) is spinforbidden from ground state reactants to ground state products. 4 eV above the ground state [181]) must play a role in this oxidation process. The most influential of these will be for a 3S– state having a (2s)2(1p)4(1d)4(2p)2(3s)0 valence electron configuration in which the 3s orbital is empty.

If this acceptor orbital is empty, the reactants can get sufficiently close so that metal electrons in orbitals having p-symmetry 20 Peter B. Armentrout Fig. 4. Molecular orbital interactions for the oxidative addition of a covalent bond to a metal center. Electron occupations for the most efficient situation are shown can back-donate into the antibonding orbital of the bond to be broken. These considerations are shown schematically in Fig. 4. Both of these acceptor-donor interactions are needed to fully activate the bond.

Armentrout Fig. 3. First (closed symbols) and second (open symbols) bond energies (in kJ mol–1) of ethene (circles) and benzene (triangles) to the first row transition metal cations Clearly the first and second bond energies are similar to one another and show the same periodic trends. In addition, these values are very similar to metal cation–CO bond energies with the exception of Mn+(CO) and Mn+(C2H4). This is reasonable as both CO and C2H4 ligands are s-donor–p-acceptor types of ligands. The weakest bond energies are for Mn+, the only metal ion where the 4s orbital is occupied in the complex [129].
