“…It is possible to graft the sulfur‐based functional groups on silica using other chemical agents instead of using organosilanes. Chlorosulfonic acids are useful in functionalizing silicas with sulfonic acid groups through nucleophilic substitution reaction . Interestingly, M. Norouzi et al.…”

“…have anchored the sulfonic acid on silica through −Si−O−B−O−S− linkage. Here, the silanols of silica are initially condensed with B(OH) 3 and then, sulfonic acid groups are introduced using chlorosulfonic acid . The other routes are also available to functionalize silicas with sulfonic acids such as the sulfonation reaction using sulfuric acid, and the ring opening of 1,4‐butane sultone and 1,3‐propane sultone .…”

“…Furthermore, OSs provide the facile mass transfer for the reactants as well as the products during the catalysis . Recently, a list of organosilanes is reported for the preparation of OSs which includes 1,4‐bis(triethoxysilyl)benzene, 4,4′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine, 1,2‐bis(triethoxysilyl)ethane, tris[3‐(trimethoxysilyl)propyl] isocyanurate, 1,3‐bis(3‐trimethoxysilylpropyl)‐imidazolium iodide and 4,4′‐[4‐(trimethoxysilanyl)butyl]‐2,2′‐bipyridine . These organosilanes evidence that OSs can possess the organic groups such as ionic liquids and bipyridyl rather than just having phenyl and ethyl groups.…”

“…Amine, sulfonic acid and IL FSs are employed as the solid reusable organocatalysts for the synthesis of many chemicals in the recent literature. Sulfonic acid FSs are found to be the very good catalysts for the synthesis of polyhydroquinolines, bis(indolyl)methanes, n‐butyl levulinate, chiral cyanohydrins, tetrahydrobenzo[ b ]pyrans, 5‐ethoxymethylfurfural and 1,2‐monoacetone‐D‐glucose . The acidic strength of sulfonic acid FSs is tuned by X. Feng et al.…”

Heterogeneous catalysis plays a key role in promoting green chemistry through many routes. The functionalizable reactive silanols highlight silica as a beguiling support for the preparation of heterogeneous catalysts. Metal active sites anchored on functionalized silica (FS) usually demonstrate the better dispersion and stability due to their firm chemical interaction with FSs. Having certain functional groups in structure, FSs can act as the useful catalysts for few organic reactions even without the need of metal active sites which are termed as the covetous reusable organocatalysts. Magnetic FSs have laid the platform where the effortless recovery of catalysts is realized just using an external magnet, resulting in the simplified reaction procedure. Using FSs of multiple functional groups, we can envisage the shortened reaction pathway and, reduced chemical uses and chemical wastes. Unstable bio‐molecules like enzymes have been stabilized when they get chemically anchored on FSs. The resultant solid bio‐catalysts exhibited very good reusability in many catalytic reactions. Getting provoked from the green chemistry aspects and benefits of FS‐based catalysts, we confer the recent literature and progress focusing on the significance of FSs in heterogeneous catalysis. This review covers the preparative methods, types and catalytic applications of FSs. A special emphasis is given to the metal‐free FS catalysts, multiple FS‐based catalysts and magnetic FSs. Through this review, we presume that the contribution of FSs to green chemistry can be well understood. The future perspective of FSs and the improvements still required for implementing FS‐based catalysts in practical applications have been narrated at the end of this review.

In this study, a novel magnetic mesoporous MCM-41 silica supported ionic liquid/palladium complex (Fe 3 O 4 @MCM@IL/Pd) with core-structure was prepared and characterized and its catalytic performance was developed under green conditions. The Fe 3 O 4 @MCM@IL/Pd was prepared via a post grafting method and was characterized using Fourier transform infrared spectroscopy, thermal gravimetric analysis, wide-and low-angle powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, vibration sample magnetometer and energy-dispersive X-ray analyses. This was applied as an efficient and recoverable nanocatalyst for the one-pot synthesis of pyrano [2,3-d]pyrimidine derivatives under ultrasonic conditions. The catalyst was magnetically recovered and reused for 12 consecutive cycles without significant loss of its activity and selectivity.
