| Research Abstract |
A zero-valent ruthenium complex having a naphthalene ligand readily releases the naphthalene to generate a 6-electron vacant site. A conjugated compound and a substituted alkene are able to coordinate to the vacant site as 4- and 2-pi donors, respectively. This catalyst therefore clearly recognizes these two substrates by the donor electrons and the cross-dimerization can be achieved. This mechanistic study reveals the oxidative coupling mechanism for present coupling reaction. To use the advantages of this mechanism, we have succeeded to develop the stereoselective reactions.
