Poly(basic ionic liquid) coated magnetic nanoparticles: High-loaded supported basic ionic liquid catalyst

A novel poly(ionic liquid) (PIL) coated magnetic nanoparticle was synthesized by distillation-precipitation-polymerization of 1-vinyl-3- ethyl imidazolium in the presence of surface modified magnetic nanoparticles. The resulting catalyst was used as magne

An eco-friendly innovative halide and metal-free basic ionic liquid catalyzed synthesis of tetrahydrobenzo [b] pyran derivatives in aqueous media: A sustainable protocol

A novel imidazolium-based highly efficient, recoverable, and reusable basic ionic liquid [PEMIM][OH] was synthesized using a very simple approach. This ionic liquid was employed as a catalyst for the multicomponent synthesis of tetrahydrobenzo[b]pyran der

A facile and efficient synthesis of tetrahydrobenzo[b]pyrans and dihydropyrano[4,3-b]pyrans derivatives using phosphate fertilizers MAP, DAP, and TSP as heterogeneous catalysts

A simple and efficient one-pot synthesis of tetrahydrobenzo[b]pyrans and dihydropyrano[4,3-b]pyrans derivatives was described. These reactions were realized through a three-component condensation of aromatic aldehyde, malononitrile, and 5,5-dimethyl-1,3-c

A new approach for the synthesis of biologically active chromene compounds using a photo catalyst TiO2-Ag

A green and efficient method for the synthesis of chromene derivatives using TiO2 doped Ag as a photocatalyst under visible light irradiation at room temperature is reported. The advantages of our method are clean reaction condition, easy workup procedure, use of eco-friendly solvent, and recyclable catalyst and most importantly higher yield of the product. The photocatalyst was found to be highly efficient for the synthesis of chromene derivatives within a short reaction time. The photocatalyst was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), and powder XRD technique and thermogravimetric analysis (TGA). In addition, the in-vitro study of helminths against S. obvelata were investigated and it was found that chromene derivatives were active against S. obvelata and showed no sign of acute toxicity in mice.
