Introduction of a novel dicationic Br?nsted acidic ionic liquid based on pyrazine and its application in the synthesis of xanthenediones and 3, 4-dihydropyrimidin-2(1H)-ones under solvent-free conditions

A novel dicationic Br?nsted acidic ionic liquid based on pyrazine has been prepared and characterized by FTIR, 1H NMR, 13C NMR, MS, thermal gravimetric and differential thermal gravimetric analysis and also Hammett acidity function.

FSM-16/AEPC-SO3H: Synthesis, Characterization and Its Application for the Catalytic Preparation of 1,8-Dioxo-octahydroxanthene and Tetrahydrobenzo[b]pyran Derivatives

A new acidic mesoporous catalyst (FSM-16/AEPC-SO3H) was successfully synthesized and characterized by FT-IR, TGA, XRD, SEM, TEM, EDS and BET techniques. The FSM-16/AEPC-SO3H showed excellent catalytic activity for the synthesis of 1,

Synthesis of xanthenediones by silica supported orthophosphoric acid (H3PO4·SiO2)

The novel protocol was developed for the synthesis of xanthenediones by silica supported orthophosphoric acid (H3PO4·SiO2) as a heterogeneous catalyst. The reported protocol is simple, scalable, mild and effective for the synthesis of xanthenediones. The (H3PO4·SiO2) catalyst demonstrated excellent catalytic activity for various substituted aromatic aldehydes. This catalyst can be reused four times without much loss in catalytic activity.

Aim and Objective: In the present work, 1, 1’-sulfinyldiethylammonium bis (hydrogen sulfate) as a novel room temperature dicationic ionic liquid was synthesized and used as a catalyst for xanthenediones synthesis. Material and Method: The dicationic ionic

A unique opportunity for the utilization of glass wastes as a resource for catalytic applications: toward a cleaner environment

Although glass recycling has been conducted since 1970s, and even though recycled glass waste has been used in the construction of various alternative products, the utilization of glass waste for catalytic applications has not been fully considered until

Neat synthesis of octahydroxanthene-1,8-diones, catalyzed by silicotungstic acid as an efficient reusable inorganic catalyst

In this article, the first use of silicotungstic acid (H4SiW12O40) as a catalyst for the synthesis of octahydroxanthene-1,8-diones by the reaction of 5,5-dimethylcyclohexane-1,3-dione (dimedone) with various aldehydes unde

Ruthenium anchored on multi-walled carbon nanotubes: an efficient and reusable catalyst for the synthesis of xanthenes

A novel and highly efficient ruthenium-based catalyst was synthesized by immobilizing Ru(CO)4 onto functionalized multi-walled carbon nanotubes. The catalyst was characterized by Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, diffuse reflectance UV–Vis spectrophotometry, inductively coupled plasma and elemental analysis. This heterogeneous catalyst was successfully applied in the multi-component synthesis of various xanthene derivatives in good to excellent yields (28 samples, up to 96?% yield) under reflux condition and ultrasonic irradiation. The prepared catalyst was recovered four times without appreciable loss of activity.
