专利号:US-7034096-B2 优先权日:2002-02-19 标题:Ring-expansion of cyclic olefins metathesis reactions with an acyclic diene 发明人:CHOI TAE-LIM; LEE CHOON WOO; KIM HYUNJIN M; GRUBBS ROBERT H 权利人:CALIFORNIA INST OF TECHN 摘要:This invention relates generally to synthetic procedures that include the step of ring-opening metathesis of cyclic olefins and reaction with an acyclic diene co-reactant to produce olefin macrocycles by ring expansion, or alternatively. The ring expansion of the cyclic olefin is provided by three types of sequential olefin metathesis (ring-opening, cross, and ring-closing olefin metathesis). More particularly, the invention pertains to synthesis of olefin macrocycles via olefin metathesis reactions using a Group 8 transition metal complex as the metathesis catalyst. Macrocycles provided herein have a variety of uses in the pharmaceutical, biomedical, organic synthesis and chemical industries, such as the production of crown ethers that are useful as metal complexing species.

专利号:US-7351781-B2 优先权日:2001-04-24 标题 :Synthesis of vinyl polymers by controlled radical polymerization 发明人:WHITE DANIELA; O'DWYER JAMES B 权利人:PPG IND OHIO INC 摘要:A controlled free radical polymerization process, which includes the steps of: adding a monofunctional iniferter compound to an oxygen-free solvent; heating the solution to a temperature sufficient to allow the iniferter compound to form two carbon centered radical residues; adding a first monomer composition comprising one or more monomers to the solution containing the radical containing residues; polymerizing the first monomer composition to form a quasi-living polymer; and optionally polymerizing a second monomer composition comprising one or more monomers, which are different than the first monomer composition. The resulting non-random copolymer having the general formula:n nφ-[-A p -B s -] t -φn nwhere A and B are different compositions of ethylenically unsaturated monomers; p is an integer from 1 to 1,000; s is an integer from 0 to 1,000; t is an integer from 1 to 100; and φ is a residue from the iniferter.
