The decline of fossil-and ore-based materials is calling for more recycling of waste into new
materials. Here, I review the recycling of ashes from biomass into reagents for chemical …

Heterogeneous catalysis plays a crucial role in many chemical processes, including
advanced organic preparations and the design and synthesis of new organic moieties …

Recently magnetic nanocatalyst has attracted considerable attention because of its unique
properties, including high performance, easy separation from the reaction mixture, and …

In this work, a new core–shell magnetic silica nanocatalyst functionalized with 3, 4-
diaminobenzoic acid (Fe3O4@ SiO2@ PTS-DABA) was successfully prepared and …

An environmentally benign protocol for diversity-oriented synthesis of functionalized
bioactive dihydropyrano [2, 3-c] pyrazole and benzylpyrazolyl coumarin derivatives has …

A novel, efficient, and recoverable nanomagnetic catalyst bearing the semicarbazide linkers,
namely, Fe3O4@ SiO2@ OSi (CH2) 3-N (3-pyridoyl sulfonic acid) semicarbazide (FSiPSS) …

In this work, nanomesoporous silica has been prepared from horsetail (Equisetum arvense),
which is a medicinal plant, with high surface area. This natural silica has been applied as a …

A transition metal/ligand/additive/promoter-free synthesis of 3-methyl-4-arylmethylene-
isoxazol-5 (4 H)-ones and the Biginelli-like synthesis is carried out in a natural acidic …

Modern synthetic chemistry encompasses the challenge of establishing sustainable, cost-
effective reaction alternatives that prevent waste and pollution and here, catalysis plays a …

Abstract α, α′-bis (substituted benzylidene) cycloalkanones were efficiently prepared from
