    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.

    摘要: Methods using catalysts and reaction conditions to produce signi ficantly improved yields (and thereby higher purity) of olefin metathesis products, with greatly reduced amounts of impurities. These techniques include in one instance reduction in temperature of reaction, and in another, the use of chemical compounds that act as reaction inhibitors of unwanted reactions to minimize or prevent formation of unwanted impurities.
