Recent developments in ruthenium-catalyzed chemo-, regio-, and stereoselective C-C bond forming reactions as well as a C-C bond cleaving reaction via an η3-allylruthenium intermediate are disclosed, in which novel ambiphilic reactivity of η3-allylruthenium complexes is discussed. In addition, a new route to cyclopentenones via ruthenium-catalyzed carbonylative cyclization of allylic carbonates with alkenes, which would be the complement of the catalytic intermolecular Pauson-Khand reaction, is also presented.
