Creation of Catalysis Based on Cooperative Effect of Transition Metals

点击翻译按钮获取中文摘要

Series of Heterodinulcear organo(or hydrido, allyl, carbene)platinum(or palladium) complexesd were prepared. Palladium(0)-catalyzed Markovnikov-type olefin insertion into insertion-inactive transition metal hydride complexes MHL´n were achieved, whose activity highly depends on steric factors of tertiary phosphine ligand employed. (E)-Isomer-selective intramolecular fluxional behavior and facile olefin induced reductive elimination of heterodinuclear allyplatinum-cobalt complexes are observed. These unusual reactivities are considered to be arisen from thermodynamic stability of the resulting allyltransition metal complexes.
