In a fifth contribution, Pierre Le Gendre et al. review the catalytic performances
of early-late bimetallic complexes. After an introduction dealing with bifunctional
and cooperative dual catalysis in which the cooperative effects arise from two
catalytic functions present in the same or two different molecules, this paper
focuses on an inventory of early-late heterobimetallic complexes in catalysis. It
includes those where the two metal centers belong to the same complex, with
bridging ligands as in the following example in which the chiral information is
provided by the titanium metal center:
