Mg(BF4)2 doped in [BMIm][BF4]: A homogeneous ionic liquid-catalyst for efficient synthesis of 1,8-dioxo-octahydroxanthenes, decahydroacridines and 14-aryl-14H-dibenzo[a,j] xanthenes

A homogeneous ionic liquid made up of 0.5 mol% Mg(BF4) 2 doped in [BMIm]BF4 was obtained from a mixture of MgCl2 and [BMIm]Cl subjected to anion exchange with NaBF4. The ionic liquid efficiently catal

Fabrication of activated carbon sulfuric acid as an excellent and novel solid acid catalyst, evaluating its catalytic activity in synthesizing 1,8-dioxo-octahydroxanthenes and 14-aryl-14H-dibenzo[a,j]xanthenes

In this work, for the first time, a novel and innovative procedure has been utilized to chemically functionalize activated carbon (AC) based on the sulfonation reaction, which can be used in catalytic reactions as a strong solid acid. For this aim, AC mus

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.

Novel ionic liquid [Et3N-SO3H][MeSo3]: Synthesis, characterization and catalytic performance for the synthesis of 14-aryl-14H-dibenzo[a,j]xanthenes

The main aim of this work is introducing a novel protic acidic ionic-liquid catalyst for organic synthesis. Thus, N,N-diethyl-N-sulfoethanaminium methanesulfonate ([Et3N-SO3H][MeSO3]) was synthesized by the reaction of triethylamine with chlorosulfonic ac
