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.

权利人:UNIV CALIFORNIA; THE MITSUBISHI CHEMICAL CORP
摘要:Efficient condition optimization for the synthesis of highly branched polymers using high throughput screening has been developed. This innovation allows rapid production of soluble, highly branched polymers with different properties (molecular weight, degree of branching, etc.). Moreover, this versatile technique has the potential to be extended to other monomer/linker systems and polymerization techniques such as emulsion or suspension polymerization, anionic polymerization and continuous flow synthesis. A resin composition is further disclosed.
