标题:Uv-vis Absorption Spectra Of 1,4-Dialkoxy-2,5-Bis[2-(Thien-2-yl)Ethenyl]Benzenes
摘要:Complex Theoretical And Experimental Studies And Quantum-Chemical Calculations Were Applied To Study The Uv-Vis Spectroscopic Features Of The Novel Compounds: Three Stereoisomers Of 1,4-Diethoxy-2,5Bis[2-(5-Methylthien-2-yl)Ethenyl]Benzene (A-C) And Ee Isomer Of 1,4-Diisopropoxy-2,5-Bis[2-(Thien-2-yl)Ethenyl]Benzene (D). These Structures Are The Derivatives Of 2,5-Bis[2-(Thien-2-yl)Ethenyl]Benzene,And Belong To A Group Of Thienyl-Ppv Family That Are Able To Polymerize Due To The Presence Of Pi-Conjugated Bonding System. It Was Established That Such Compounds During Electropolymerization Are Strongly Dependent On Their Stereochemistry And On The Eventual Presence Of Substituents In Alpha-Positions. Of The Tiophene Ring. We Have Obtained A Good Agreement Between The Theoretically Simulated Optical Within A Framework Of Tddft Approach And Experimentally Measured Data. Influence Of Pmma Polymer Matrices On The Uv-Vis Spectra Is Explored. It Is Shown That A Red Wavelength Spectral Shift Is Observed Only For D Compounds And Agreement Between Calculated And Experimental Spectral Data Is Sufficiently Good. This May Indicate On Different Influence Of Local Polymer Matrix Field On The Spectral Behaviors Of The Chromophores With Different Stereochemistry. (C) 2008 Elsevier B.V. All Rights Reserved.

标题:Synthesis of anthracyclines
发明人：JOHNSON FRANCIS; KIM KYOUNG S
权利人:RESEARCH CORP
摘要:There is provided a novel method of synthesizing certain heterocyclic quinones. In particular there is provided a novel and regiospecific synthesis of 9-acetyl-6,11-dihydroxy-4-methoxy-7,8,9,10-tetrahydronaphthacene-5,12-quinone (7,9-dideoxydaunomycinone) which is known intermediate in the synthesis of daunomycinone. There is also provided a method of preparing analogs of 7,9-dideoxydaunomycinone which thus provide for the preparation of known and desired analogs of daunomycinone. Daunomycinone is a known compound which is an intermediate in the preparation of the clinically accepted naturally-occurring antitumor antibiotics daunomycin and its derivitive adriamycin.

标 题 :Synthesis of alkoxy and phenoxy substituted aryl sulfides
发明人：HANSON HARRY T; SAPP JR JOHN B
权利人:CELANESE CORP
摘要:Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.

标题:Synthesis of stable nitrile oxide compounds
发明人：PARKER DANE KENTON
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention discloses a process for the synthesis of stable aryl nitrile oxides which comprises the sequential steps of (1) halomethylating a halomethyl group onto a substituted aromatic compounds wherein said halomethyl group is halomethylated onto a position that is ortho to at least one of the substituent groups on the substituted aromatic compound; (2) converting the ortho halomethylated-substituted aromatic compound into an ortho-substituted aromatic aldehyde by reacting the ortho halomethylated-substituted aromatic compound with a salt selected from the group consisting of sodium 2-nitropropane and potassium 2-nitropropane in a lower alcohol solvent; (3) converting the ortho-substituted aromatic aldehyde into an ortho-substituted aromatic; and (4) converting the ortho-substituted aromatic oxime into the ortho-substituted aryl nitrile oxide by reacting the ortho-substituted aromatic oxime with an aqueous sodium hypochlorite solution.
