Synthesis and spectroscopic characterization of new Schiff bases containing the benzo-15-crown-5 moiety.
New crown ether Schiff base derivatives were prepared by the condensation of 4'-formylbenzo-15-crown-5 or 4'-formyl-5'-hydroxybenzo-15-crown-5 with 1,2-bis(2-aminophenoxy)ethane. The structures of these new compounds were confirmed on the basis of elemental analysis, IR, (1)H- and (13)C-NMR, UV-Vis and mass spectroscopic data.
متن کاملN-phenylaza-15-crown-5 as Ionophore in PVC-Matrix for Fe2+ - Selective Sensor
The preparation of polymer membrane selective to Iron(II) ion and its application to ion-selectiveelectrode is reported here. PVC membrane contains Iron–selective N-phenylaza-15-crown-5 asionophore. The membrane electrode is highly selective to Iron(II) ion and exhibit good linearresponse over a wide concentration range of 1.0 × 10-2 to 1.0 × 10-6 M with Nernstian slope of29.2 ± 0.6 mV per deca...

Indandione 1 was brominated to yield 2-bromoIndandione 2 which on further reacted with substituted thiocarbamides, carbamides, 2-aminothiophenols, 2-aminophenol and triazoles to furnished 3-substituted aniline-2-thia-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 3, 3-substituted aniline-2-oxa-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 4, 2-Thia-5-aza-9-oxo-3,4-(3’-substitut...
متن کاملwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
