Preparation of Alkyl Formates from Corresponding Alcohols using Ethyl Formate Catalyzed by Poly(4-vinylpyridinium tribromide) under Neutral and Solvent-Free Conditions

Synthesis, characterization, and application of Fe3O4-SA-PPCA as a novel nanomagnetic reusable catalyst for the efficient synthesis of 2,3-dihydroquinazolin-4(1H)-ones and polyhydroquinolines

“…In continuation of our recent success in the introduction of new catalysts, [16][17][18][19][20] in the present article we describe the preparation of sulfamic acid-functionalized Fe 3 O 4 (Fe 3 O 4 -SA-PPCA) with high magnetic sensitivity and application in multicomponent reactions (Scheme 1).…”

An Efficient and Facile Procedure for Synthesis of Acetates from Alcohols Catalyzed by Poly(4-vinylpyridinium tribromide)

“…In continuation of our studies in application of poly(4-vinylpyridinium tribromide) in organic reactions [19][20][21], we have found that combination of acetic anhydride as acylating agent with catalytic amounts of poly(4-vinylpyridinium tribromide) could be an efficient protocol for conversion of alcohols into their corresponding acetates.…”

Polyvinylpolypyrrolidoniume Tribromide as an Efficient Catalyst for the Acetylation of Alcohols and Phenols

“…In a continuation of our ongoing efforts to develop novel applications of polymeric reagents or catalysts in organic reactions [19][20][21][22][23][24], polyvinylpolypyrrolidoniume tribromide was investigated as a green catalyst for the preparation of O-alkyl and aryl acetylated compounds.…”
