    摘要: Synthetic methods for the in-situ formation of olefin metathesis catalysts are disclosed, as well as the use of such catalysts in metathesis reactions of olefins and olefin compounds. In one aspect, a method is provided for synthesizing an organometallic compound of the formula (I); comprising contacting a precursor compound of the formula (X 1 X 2 ML j L 1 k L 3 m ) i with an acetylenic compound of the formula comprising a chelating moiety, optionally, in the presence of a neutral electron donor, wherein M is a Group 8 transition metal, L, L 1 , L 2 , and L 3 are neutral electron donors, X 1 and X 2 are anionic ligands, j is 1, 2, or 3; k is zero, 1, or 2; m is zero or 1; n is 1 or 2; and i is an integer; with the proviso that k is zero when the precursor compound is contacted with the acetylenic compound in the presence of the neutral electron donor, and R 1 and R 2 are independently selected from hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, and functional groups, wherein R1 and R2 are linked and together form one or more cyclic groups, R 2 and L 2 are linked and together form one or more cyclic groups, and any other two or more of X 1 , X 2 , L 1 , L 2 , L 3 , R 1 , and R 2 can be taken together to form one or more cyclic groups.

    摘要: This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35 °C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.

    摘要: Disclosed are improved methods for conducting metathesis utilizing polyunsaturated fatty acid compositions (e.g., polyunsaturated fatty acid polyol esters, polyunsaturated fatty acids, polyunsaturated fatty esters, and mixtures), such as those found in naturally occurring oils and fats, as the starting material. The inventive methods involve hydrogenation of polyunsaturated fatty acid compositions prior to metathesis, thereby providing partially-hydrogenation compositions having a relatively higher amount of monounsaturated fatty acid species. The partially hydrogenated composition can then be subjected to metathesis to provide a metathesis product composition containing industrially useful compounds.
