Title:
METAL COMPLEX AND SUPPORTED METAL COMPLEX HAVING DISILOXANE AS LIGAND, PREPARATION METHOD THEREFOR, AND SUPPORTED METAL CATALYST PREPARED USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/142252
Kind Code:
A1
Abstract:
A metal complex represented by general formula (1). (In the formula, 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 from 0 to 2 representing the number of ligands, and R1-R4 represent an organic group.) The metal complex can be immobilized to an inorganic oxide while retaining the skeleton structure thereof to form a supported metal complex, and as a result, the supported metal complex is able to maintain the same level of catalytic activity provided in the original metal complex. In addition, by calcining a supported metal complex obtained in such a manner, it is possible to obtain a supported metal catalyst having catalytic activity which is greatly improved over conventional supported metal catalysts.
