标题 :Synthesis of open metal carbonyl clusters
发明人：KATZ ALEXANDER S; KUPERMAN ALEXANDER; OKRUT ALEXANDER; RUNNEBAUM RON C; OUYANG XIAOYING
权利人:CHEVRON USA INC; UNIV CALIFORNIA
摘要:The present invention is directed to the synthesis of novel stable open metal clusters by selective oxidation of bound ligands. The synthesis comprises, for example, using an amine based oxidant for decarbonylation of specific carbonyl ligands. The synthesis can also comprise further removal of a bound amine group by an acid. The resulting metal cluster contains a coordinatively unsaturated site comprising a carbonyl vacancy. The resulting metal cluster can be used as a catalyst in a variety of chemical transformations.

标题:Process for the synthesis of isocyanates and of isocyanate derivatives

摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

标题 :One-pot synthesis of group 8 transition metal carbene complexes useful as olefin metathesis catalysts
发明人：GRUBBS ROBERT H; MORGAN JOHN P; BENITEZ DIEGO; LOUIE JANIS
权利人:CALIFORNIA INST OF TECHN
摘要:The invention provides a novel method for synthesizing transition metal carbene complexes useful as olefin metathesis catalysts. The method is a convenient one-pot synthesis in which transition metal carbenes are prepared in high yield from readily available starting materials via a dihydrogen complex containing two different anionic ligands, preferably a phosphine and a heteroatom-stabilized carbene. The invention additionally provides a method for synthesizing precursors to carbene ligands useful, inter alia, in the aforementioned one-pot synthesis. The precursors are in the form of trichloromethyl adducts of the formula L 1 -CCl 3 , where L 1 is a heteroatom-stabilized carbene ligand, and are prepared by contacting an unsaturated, ionized analog of L-CCl 3 with a non-nucleophilic base in the presence of chloroform.
