Solvent-Free Synthesis and Spectral Linearity of Some (E)-2-(substituted benzylideneamino)-N-(3-chloro-4-fluorophenyl)-hexahydro-2<i>H</i>-cyclopenta[b]thiophene-3-carboxamides
Abstract:Some(E)-2-(substituted benzylideneamino)-N-(3-chloro-4-fluorophenyl)-hexahydro-2H-cyclopenta [b]thiophene-3-carboxamide derivatives have been synthesized by SiO 2 :H 3 PO 4 catalyzed solventfree condensation of 2-amino-N-(3-chloro-4-fluorophenyl)-hexahydro-2H-cyclopenta [b]thiophene-3-carboxamide and various substituted benzaldehydes in microwave irradiation. The yield of the iminecarboximido derivatives has been found to be more than 85 %. The purity of all imine-carboximido derivatives has been checked using… Show more
