Furan derivatives. ЬХХП. Synthesis and some properties of l-(5-nitro-2-furyl)- -2- (5-aryl-2-furyl)ethylenes
Wittig reaction has recently been applied also in the preparation of 5-nitrofuran derivatives of ethylene [1—5]. The quoted syntheses were accomplished starting either from 5-nitrofurfuryl halides which were converted into 5-nitrofurfurylidenephosphoranes and subsequent condensation of the latter with carbonyl compounds [1—4], or the intermediate phosphoranes were prepared from other furfuryl h...
متن کاملThermodynamic properties of 5(nitrophenyl) furan-2-carbaldehyde isomers.
BACKGROUND The aim of the current work was to determine thermo dynamical properties of 5(2-nitro phenyl)-furan-2-carbaldehyde, 5(3-nitro phenyl)-furan-2-carbaldehyde and 5(4-nitro phenyl)-furan-2-carbaldehyde. RESULTS The temperature dependence of saturated vapor pressure of 5(2-nitro phenyl)-furan-2-carbaldehyde, 5(3-nitro phenyl)-furan-2-carbaldehyde and 5(4-nitro phenyl)-furan-2-carbaldehy...
متن کاملSupramolecular structures of three isomeric 2-chloro-N-(nitrophenyl)nicotinamides.
Molecules of 2-chloro-N-(2-nitrophenyl)nicotinamide, C12H8ClN3O3, are linked by two C-H...O hydrogen bonds into a chain of edge-fused R(2)(2) (14) and (4)(4) (24) rings. In 2-chloro-N-(3-nitrophenyl)nicotinamide monohydrate, C12H8ClN3O3.H2O, the molecules are linked by a combination of N-H...O, O-H...O and O-H...N hydrogen bonds into a chain of edge-fused rings containing two distinct types of ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولSynthesis and studies on antidepressant and anticonvulsant activities of some 3-(2-furyl)-pyrazoline derivatives.
Twelve 1-phenyl-, 1-thiocarbamoyl- and 1-N-substituted thiocarbamoyl-3-(2-furyl)-5-phenyl/(2-furyl)-2-pyrazoline derivatives were synthesized. The chemical structures of the compounds were proved by IR, (1)H NMR, Mass spectrometric data and microanalyses. The antidepressant activities of the compounds were investigated by Porsolt's behavioural despair (forced swimming) test on albino mice. 1-N-...
