  • Patent number: 10752579
    Abstract: A method of production of carbamic acid ester has a high yield and high selectivity and is superior in economy. The method of production of a carbamic acid ester includes reacting an amine, carbon dioxide, and an alkoxysilane compound in the presence of a catalyst containing a zinc compound or an alkali metal compound or in the presence of an ionic liquid. A carbamic acid ester is produced, for example by reacting aniline, carbon dioxide, and tetramethoxysilane at a temperature of 150 to 180° C. in the presence of zinc acetate and 2,2?-bipyridine.

The resin composition is usable as an addition-reaction catalyst capable of imparting sufficient storability and quick curability to an addition-reaction curable composition. In the formula, L represents a ligand selected from carbon monoxide, an olefin compound, an amine compound, a phosphine compound, an N-heterocyclic carbene compound, a nitrile compound, and an isocyanide compound; and n represents the number of Ls and an integer from 0 to 2.

  • Publication number: 20200188897
    Abstract: An organometallic complex catalyst is disclosed for use in a cross-coupling reaction. In formula (1), M is the coordination center and represents a metal atom such as Pd or an ion thereof. R1, R2, and R3 may be the same or different and are a substituent such as a hydrogen atom. R4, R5, R6, and R7 may be the same or different and are a substituent such as a hydrogen atom. X represents a halogen atom. R8 represents a substituent that has a ? bond and 3-20 carbon atoms. With regard to the electron-donating properties of R1-R7 with respect to the coordination center M of the ligand containing R1-R7 that is indicated in formula (2), R1-R7 are arranged in combination such that the TEP value obtained from infrared spectroscopy shifts toward the low frequency side compared to the TEP value of the ligand of formula (2-1).

  • Patent number: 10213777
    Abstract: A metal complex represented by the following Formula (1): (wherein M represents palladium or platinum; L represents a ligand selected from carbon monoxide, an olefin compound, an amine compound, a phosphine compound, an N-heterocyclic carbene compound, a nitrile compound and an isocyanide compound; n represents an integer of 0 to 2 showing the number of the ligand; and each of R1 to R4 represents an organic group). The metal complex described above can be fixed on an inorganic oxide while maintaining a skeletal structure thereof to obtain a supported metal complex, and this makes it possible to allow the supported metal complex to maintain the same catalytic activity as that of the original metal complex. Also, calcining the supported metal complex obtained in the manner described above makes it possible to obtain a supported metal catalyst which is improved in catalytic activity to a greater extent than conventional supported metal catalysts.
