All the compounds have been characterized by their percentage yield, melting point, elemental analysis, ¹H NMR and ¹³C NMR spectra and IR spectra. These compounds have been screened for their antimicrobial activities<i style="">.</i> <br/> <br/>Page(s): 1170-1173 Wed, 29 Jul 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/5791 Title: Tetraethylammonium superoxide induced Michael addition of active methylene compounds to chalcones <br/> <br/>Authors: Raghuvanshi, Raghvendra Singh; Singh, Krishna Nand <br/> <br/>Abstract: Michael addition of active methylene compounds to chalcones using <i style="">in-situ</i> generated tetraethylammonium superoxide results in the formation of Michael adducts in 69-84% yield under mild reaction conditions, at room temperature. <br/> <br/>Page(s): 1161-1163 Wed, 29 Jul 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/5790 Title: Synthesis and characterization of 5-(2-nitro-1-arylpropyl)-4-aryl-1,2,3-selenadiazoles <br/> <br/>Authors: Saravanan, S; Amuthavalli, A; Muthusubramanian, S <br/> <br/>Abstract: The synthesis<b style=""> </b>and characterization of new 5-(2-nitro-1-arylpropyl)<b style="">-</b>4-aryl-1,2,3-selenadiazoles, obtained from the <img src='/image/spc_char/alpha.gif'>-functionalised semicarbazones are described.
