Abstract: In this method, at first the synthesis of 2,3-dihydro-1H-carbazol-4(9H)-one product by the condensation of (Z)-3-(2-phenylhydrazono)cyclohexanone in the presence of (SBA-Pr-SO3H) as nanoporous solid acid catalyst, acid acetic glacial and ethanol as solvent under reflux conditions is reported. (SBA-Pr-SO3H) nanoporous solid acid catalyst was used as an effective catalyst for the synthesis of Carvedilol from the reaction of 4-oxiranylmethyoxy-9H-carbazole and 2-(2-methoxyphenoxy)ethanamine in the presence of monoglyme solvent. This synthesis afforded under ring opening of 4-oxiranylmethyoxy-9H-carbazole with 2-(2-methoxyphenoxy)ethanamine by above nano-catalyst. Heterogeneous reaction conditions, easy procedure, short reaction time, and high yields are some important advantages of this method.Abstract: In this method, at first the synthesis of 2,3-dihydro-1H-carbazol-4(9H)-one product by the condensation of (Z)-3-(2-phenylhydrazono)cyclohexanone in the presence of (SBA-Pr-SO3H) as nanoporous solid acid catalyst, acid acetic glacial and ethanol as solvent under reflux conditions is reported.

Abstract: Different Pyrazoline derivatives were synthesized by cyclization of substituted chalcone derivatives in presence of hydrazine hydrate. A series of novel 1,3,5-triaryl pyrazoline derivatives has been synthesized by the reaction of chalcone and phenylhydrazine in the presence of Silica-supported Preyssler Nanoparticles, H14[NaP5W30O110]/SiO2, Preyssler H14[NaP5W30O110] and Keggin heteropolyacids, H3PW12O40, H7[PMo8V4O40], H6[PMo9V3O40], H5[PMo10V2O40], H4[PMo11VO40], H3[PMo12O40] as catalyst under aqueous conditions is described. The best conditions were observed using Preyssler and Silica-supported Preyssler Nanoparticles as catalysts. The catalyst is recyclable and reusable. The structures of compounds obtained were determined by IR and 1H NMR spectra.Abstract: Different Pyrazoline derivatives were synthesized by cyclization of substituted chalcone derivatives in presence of hydrazine hydrate.
