专利号:WO-9515082-A1 优先权日:1993-12-02 标 题:Utilization of phenyl compounds for the control of phytoparasite nematodes 发明人:GONZALEZ PEREZ JOSE ANTONIO; ESTEVEZ BRAUN ANA; GUTIERREZ RAVELO ANGEL; ESTEVEZ REYES RAFAEL 权利人:UNIV LA LAGUNA; GONZALEZ PEREZ JOSE ANTONIO; ESTEVEZ BRAUN ANA; GUTIERREZ RAVELO ANGEL; ESTEVEZ REYES RAFAEL 摘要:The invention relates to the utilization of phenyl compounds for controlling phytoparasites nematodes. It has been discovered that phenyl compounds with substituants which include a vinylic or acetylenic group conjugated with an oxygenated function or with sulfur have a potent nematicide action on phytoparasite nematodes. One object of the invention is to define substances which have not been previously disclosed and which can be used to control phytoparasite nematodes. Another object of the invention is to find new utilizations of mono- and bi-substituted phenyl compound derivatives which have not been described before as nematicides. Said utilizations are not evident when considering the state of the art. The object of this invention is to apply on an industrial scale the phenyl compounds since they may be obtained by means of simple chemical synthesis processes.

专利号:US-8034982-B2 优先权日:2007-04-11 标 题 :Isotopically tagged synons from 2 carbon precursors 发明人:MARTINEZ RODOLFO A 权利人:NEW MEXICO HIGHLANDS UNIVERSITY 摘要:The use of vinyl sulfides, sulfoxides and sulfones in synthetic chemistry for the production of a wide variety of materials is well known. For example, phenyl vinyl sulfides, sulfoxides and sulfones have been used for the synthesis of important heterocycles, in combinatorial chemistry and as Diels-Alder adducts. Although these compounds have been used extensively for a variety of applications, the isotopically labeled versions have not been reported. A simple route for the isotopically labeled production of these important building blocks has been developed.
专利号:US-7687635-B2 优先权日:2002-01-22 标 题:Metal complexes useful in metathesis and other reactions 发明人:VERPOORT FRANCIS WALTER CORNELIUS; DE CLERCQ BOB 权利人:TELENE S A S 摘要:This invention provides metal complexes being useful as catalyst components in metathesis reactions and in reactions involving the transfer of an atom or group to an ethylenically or acetylenically unsaturated compound or another reactive substrate and, with respect to a sub-class thereof, for the polymerisation of α-olefins and optionally conjugated dienes, with high activity at moderate tempera-tures. It also provides methods for obtaining polymers with very narrow molecular weight distribution by means of a living reaction. It also provides methods for making said metal complexes and novel intermediates involved in such methods. It further provides derivatives of said metal complexes which are suitable for covalent bonding to a carrier, the product of such covalent bonding being useful as a supported catalyst for heterogeneous catalytic reactions. It also provides a direct one-step synthesis of pyrrole, furan and thiophene compounds from diallyl compounds.
