Sulfonic acid functionalized mesoporous SBA-15 for one-pot synthesis of substituted aryl-14H-dibenzo xanthenes and bis(indolyl) methanes

The comparative catalytic activity studies of biologically and industrially important compounds such as Xanthenes and bis (indolyl) methanes were evaluated over propylsulfonic acid functionalized SBA-15/SO3H. The material was characterized via

Design and characterization of [(Et)3?N-H]FeCl4 as a nanomagnetic ionic liquid catalyst for the synthesis of xanthene derivatives under solvent-free conditions

The triethylamine-based nanomagnetic ionic liquid, [(Et)3?N-H]FeCl4, was synthesized, and its structural and chemical characteristics were detected. The thermogravimetric analysis indicated its high thermal stability with a decomposi

Solvent-free synthesis of 14-aryl-14H-dibenzo[a-j]xanthenes using Fe3O4@Al2O3@SiO2@Fe2O3 as a green catalyst

We report, a novel, green, nano-sized particles as a sandwich nano-capsule multilayer catalyst (SNC@MC) [Fe3O4@Al2O3@SiO2@Fe2O3] for the efficacious one-pot synthesis of 14-aryl-

Nano-ZnO Impregnated on Starch—A Highly Efficient Heterogeneous Bio-Based Catalyst for One-Pot Synthesis of Pyranopyrimidinone and Xanthene Derivatives as Potential Antibacterial Agents

Abstract: A new method has been proposed for the synthesis of pyranopyrimidinone andxanthene derivatives using zinc oxide–starch nanocomposite as catalyst undermicrowave irradiation. The ZnO–starch nanocomposite was characterized by X-raydiffraction and s

High acidity cellulose sulfuric acid from sulfur trioxide: A highly efficient catalyst for the one step synthesis of xanthene and dihydroquinazolinone derivatives

A cellulose sulfonate catalyst (HS-cellulose sulfonate) with high stability, excellent catalytic activity and high acidity value (about 1.55 mmol g-1) was successfully prepared by SO3 gas phase sulfonation. The basic morphology and nanostructure of the catalyst were determined by HRTEM, XRD, IR, TG, etc. In addition, the catalyst was applied to the catalytic reaction of a dihydroquinazolinone derivative and a xanthene compound, and very valuable results were obtained. The development and preparation of cellulose sulfonate catalysts provide a good approach for the development and application of cellulose, and also an important application of green organic catalytic synthesis methodology.
