Reusable Silica supported Perchloric acid and potassium bisulphate as green catalysts for thiocyanation of aromatic compounds under solvent free conditions
Reusable silica supported perchloric acid and potassium bisulphate have been prepared and explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and hetero aromatic compounds in good yields. Reacti...
متن کاملSolvent-Free Synthesis of Aryl Iodide Using Nano SiO2/HIO4 as a Reusable Acid Catalyst
An efficient and environmentally benign method for the synthesis of aryl iodides have been developed by diazotization of aromatic amines with NaNO2 and nanosilica periodic acid (nano-SPIA) as a green catalyst via grinding followed by a sandmeyer iodination by KI under solvent-free conditions at room temperature. The ensuing aryl diazonium salts supported on nano-SPIA were sufficiently stable ...
متن کاملSilica Boron Sulfonic Acid as Heterogeneous and Highly Efficient Solid Acid Catalyst For the Preparation of Hantzsch 1,4-dihydropyridines Under Solvent-Free
Silica boron sulfonic acid [SiO2–B(OSO3H)3] as an inexpensive, reusable, and Lewis and Brønsted acid catalyst was successfully synthesized, and used for the one-pot three-components synthesis of biologically active substituted Hantzsch 1,4-dihydropyridine derivatives in the absence of solvent at 90ºC. Silica boron sulfonic acid is attractive and efficient, because it plays in two role as a Lew...
متن کاملTannic acid: A Green Catalyst for the Eco-friendly Synthesis of 2,3-dihydroquinazolin-4(1H)-ones under Solvent Free Conditions
A new, facile, cost effective, and eco-friendly protocol is reported for the synthesis of 2,3-dihydroquinazoline-4-(1H)-ones exploring tannic acid as a novel, inexpensive, andbiodegradable catalyst. A variety of dihydroquinazolins were prepared from aromatic aldehydesand anthranilamide using catalytic amount of tannic acid under solvent free conditions.Operational simplicity, high yield, and hi...
متن کاملMarine Sponge/H3PO4: As a Naturally Occurring Chiral Catalyst for Solvent-free Fischer-Indole Synthesis
BACKGROUND A new and efficient method have been developed for the synthesis of different indole derivatives from various ketones, having at least one hydrogen atom attached to each of their α-carbon atoms, and hydrazines in solvent-free conditions, using marine sponge/H3PO4 as a naturally occurring chiral catalyst. OBJECTIVES This study recommended the use of marine sponge/H3PO4 as a naturall...
