Conjugated dienes undergo metallation to give the 1,4-adduct 198 and the dimerization-1,8-addition product 199 with main group metal compounds. The reaction proceeds by oxidative addition of main group metal compounds to transition metal complexes. Reactive allylmetal compounds 198 and 199 as useful synthetic intermediates are prepared by this methods. 

Valence d electrons of transition metals impart special properties (e.g., color and substitution reactivity) to coordination complexes. These valence electrons can also be removed completely from (oxidation) or added to (reduction) metal d orbitals with relative facility. Such oxidation-reduction (redox) reactions, like substitution reactions, are integral to metal complex reactivity. Consider the role of redox chemistry in the synthesis of [Co(NH3)5C1]+, equation (1.8). In general, the preparation of cobalt(III) complexes (Chapters 2 and 5) starts with substitutionally labile cobalt(II) salts that are combined with appropriate ligands with subsequent oxidation of the metal by H202 or 02 to the substitutionally inert (robust) +3 state.

A fifth paper on this reaction seeks to clear up discrepancies between two sets of activation parameters reported for the k and k terms of this rate law. This paper also briefly discusses reactivities of 0x0- and hydroxo-bridged transition-metal complexes. Reactivities of these compounds can be compared with those for similar actinide species through kinetic results for decomposition of, for example, the [U020H]a + dimer, and the peroxo-bridged plutonium species [Pu—O2—PuOH] +. The rate of decomposition of this last complex is proportional to hydrogen ion concentration— there is just one acid-catalysed path here, in contrast to the parallel pH-dependent and pH-independent paths for the [Fe(OH)]a + dimer.
