Reaction of 2 , 5 - Disubstituted - l , 3 , 4 - oxadiazoles
Some 5-aryl-2-mercapto-1,3,4-oxadiazole (I) reacted with maleic anhydride, maleic acid and p-benzoquinone affording 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic anhydrides (II), 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic acids (III) and 2-(2,5-dihydroxyphenylthio)-5-aryl-l,3,4-oxadiazoles (IV), respectively. Treatment of 2-methylthio-5-phenyl-l,3-oxadiazole (V) with amines gives 2-[(alkyl or ar...
متن کاملA highly efficient one-pot reaction of 2-(gem-dibromovinyl)phenols(thiophenols) with K4Fe(CN)6 to 2-cyanobenzofurans(thiophenes).
2-Cyanobenzofurans and 2-cyanobenzothiophenes were prepared through an efficient one-pot Ullmann-reaction/cyanation reaction. In the presence of CuI/Na(2)CO(3)-Pd(OAc)(2)/PPh(3) in DMF, the reaction of 2-(gem-dibromovinyl)phenols and 2-(gem-dibromovinyl)thiophenols with K(4)Fe(CN)(6), as non-toxic and user-friendly cyanating reagent, proceeded smoothly to generate the corresponding 2-cyanobenzo...
متن کامل[6 + 2] AND [4 + 2] CYCLOADDITION REACTION OF DIPHENYLKETENE AND CYCLOHEPTATRIENE
The cycloaddition reaction of diphenylketene and cycloheptatriene is studied. The reaction proceeds via a highly asynchronous reaction path to the zwitterionic 6 as intermediate. Subsequent CC- bond formation yields 8, 8 diphenylbicyclo [4. 2. I] nona-2, 4-dien-7-one (1) and 7,7-diphenylbicycol [3.2.2] nona-2, 8-dien-ri-one (2) in a 1:1 ratio as formal [6+2] and [4+2] cycloaddition products
متن کامل2 00 6 Fractional Reaction - Diffusion Equations
In a series of papers, Saxena, Mathai, and Haubold (2002, 2004a, 2004b) derived solutions of a number of fractional kinetic equations in terms of generalized Mittag-Leffler functions which provide the extension of the work of Haubold and Mathai (1995, 2000). The subject of the present paper is to investigate the solution of a fractional reaction-diffusion equation. The results derived are of ge...
متن کامل2 00 6 Reaction - Diffusion Systems Andnonlinearwaves
The authors investigate the solution of a nonlinear reaction-diffusion equation connected with nonlinear waves. The equation discussed is more general than the one discussed recently by Manne, Hurd, and Kenkre (2000). The results are presented in a compact and elegant form in terms of Mittag-Leffler functions and generalized Mittag-Leffler functions, which are suitable for numerical computation...
