Abstract
Internal dienes (including supported versions) and their Periodic Groups IX, X and Pt Group Metal Complexes as catalysts for hydrosilylation/coupling reactions. A process for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl or siloxy hydride with (b) an unsaturated compound in the presence of (c) one or more platinum complex containing said internal dienic ligand or (d) a platinum compound and one or more said internal dienic ligand additive. For Ru, Os, Co, Rh, Ir, Ni, or Pd, catalyzed processes such as C—C/C—N or C—O coupling comprising reacting (a) an aromatic halide/vinyl halide/an aromatic triflate with (b) a primary/secondary amine/amide, an alcohol/aryl boronic acid/aryl boronate/vinyl halide or an activated olefin in the presence of (c) a Group IX or X or Pt Group metal complex containing said dienic ligand(s) or (d) a suitable compound of these metals and of one or more said internal dienic ligand additive.
