专利号:US-9896336-B2 优先权日:2008-06-11 标 题:Bromine-facilitated synthesis of fluoro-sulfur compounds 发明人:WINTER ROLF 权利人:AVANTBIO CORP 摘要:Described herein are methods for the bromine-facilitated synthesis of fluoro-sulfur compounds, that include SF 4 , SF 5 Cl, SF 5 Br and SF 6 . The methods described herein generally require lower temperature and pressure, produce higher yields, require less time, do not use corrosive or costly reactants and solvents that are commonly used in the synthesis of the fluoro-sulfur compounds, and do not produce deleterious waste products when compared to previously-used methods.
专利号:US-6159673-A 优先权日:1996-07-17 标 题:Oxonol compound, light-sensitive material and process for the synthesis of oxonol compound 发明人:NISHIGAKI JUNJI; DEGUCHI YASUAKI 权利人:FUJI PHOTO FILM CO LTD 摘要:An oxonol compound is represented by the following formula (I): in which Z is an atomic group that forms a cyclic amide ring; each of W1 and W2 independently is an atomic group that forms an acidic nucleus ring; and M is a cation. Other oxonol compounds, a light-sensitive material containing an oxonol compound and a process for the synthesis of an oxonol compound are also disclosed.
专利号:US-4658031-A 优先权日:1982-10-07 标 题:Synthesis of 2-substituted-5-methyl-pyridines and intermediates therefor 发明人:HARTMANN LUDWIG A; STEPHEN JOHN F 权利人:ICI AMERICA INC 摘要:A process for the synthesis of compounds which are known intermediates for the pyridyloxyphenoxy herbicies as well as intermediates used in the process. Propionaldehyde and an acrylic compound, two readily available starting materials, are reacted to form a 2-formylpentanoic compound which is cyclized to a dihydro pyridone which is then oxidized to the 2-hydroxy pyridine. The hydroxypyridine may be halogenated to a 2-halopyridine.
