    摘要： A carrier for carrying an osmium oxide comprising an aromatic polyolefin polymer having a group shown by the general formula [1] as a substituent on the aromatic ring of said polyolefin polymer: —A′—O(—A—O)n—R[1] (wherein A is an alkylene group; A′ is a direct link or an alkylene group; R is an aryl group; and n is an integer of 1 to 10), an osmium oxide carried by the carrier for carrying an osmium oxide and a method for producing the osmium oxide carried by said carrier are disclosed. Since the osmium oxide carried by the carrier of the present invention has a hydrophilic group, in an oxidation reaction and an asymmetric oxidation reaction, particularly in a heterogeneous solvent system, the osmium oxide carried by the carrier of the present invention enables to produce a diol compound easily and in a high optical yield.

    摘要： The present invention relates to novel hexacoordinated metathesis catalysts and to methods for making and using the same. The inventive catalysts are of the formula wherein: M is ruthenium or osmium; X and X1 are the same or different and are each independently an anionic ligand; L, L1′ and L2 are the same or different and are each independently a neutral electron donor ligand; and, R and R1 are each independently hydrogen or a substituent selected from the group consisting of C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl and C1-C20 alkylsulfinyl and silyl. Optionally, each of the R or R1 substituent group may be substituted with one or more moieties selected from the group consisting of C1-C10 alkyl, C1-C10 alkoxy, and aryl which in turn may each be further substituted with one or more groups selected from a halogen, a C1-C5 alkyl, C1-C5 alkoxy, and phenyl. Moreover, any of the catalyst ligands may further include one or more functional groups. Examples of suitable functional groups include but are not limited to: hydroxyl, thiol, thioether, ketone, aldehyde, ester, ether, amine, imine, amide, nitro, carboxylic acid, disulfide, carbonate, isocyanate, carbodiimide, carboalkoxy, carbamate, halogen, alcohol, sulfonic acid, phosphine, imide, acetal, ketal, boronate, cyano, cyanohydrin, hydrazine, enamine, sulfone, sulfide, and sulfenyl. In certain embodiments, at least one of L, L1′ and L2 is an N-heterocyclic carbene ligand.
