C–C Bond Formation on Activation of Alkynes and Alkenes with (C5R5)Ru Catalysts

Abstract : Electron-rich ruthenium(II) catalysts of type (C5R5)XRuL n are used to perform selective carbon–carbon bond formation by combination of simple substrates such as the coupling of functional alkynes and alkenes with a variety of unsaturated molecules (alkynes, diynes, alkenes, dienes) or non-unsaturated molecules such as alcohols or water, often with atom economy. Various selective transformations are developed and can provide access to high multifunctional molecules. These reactions often proceed via an initial oxidative coupling leading to a ruthenacycle intermediate
