权利人:ELEVANCE RENEWABLE SCIENCES
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.

标 题 :Synthesis of macrocyclic polymers by ring insertion polymerization of cyclic olefin monomers
发明人：GRUBBS ROBERT; BIELAWSKI CHRIS; BENITEZ DIEGO
权利人:CALIFORNIA INST OF TECHN
摘要:A method for synthesizing cyclic polymers using transition metal alkylidene complexes as reaction catalysts is provided, wherein the complexes contain a cyclic group. Polymerization is carried out on the catalyst, using cyclic olefin monomers that undergo ring insertion polymerization, and no linear intermediates are generated. Following completion of polymerization, the cyclic polymer detaches from the complex via an intramolecular chain transfer reaction and the catalytic complex is regenerated. The invention also provides novel transition metal alkylidene complexes useful as catalysts in the aforementioned process, as well as novel cyclic hydrocarbons.
