Preparation of an improved sulfonated carbon-based solid acid as a novel, efficient, and reusable catalyst for chemoselective synthesis of 2-oxazolines and bis- …
Abstract A highly sulfonated carbon as an efficient, recyclable, nontoxic, and green solid acid catalyst was readily synthesized by simultaneous sulfonation, dehydration, and carbonization of sucrose in sulfuric acid and was characterized by FT-IR, TG-DTG, XRD, and CHNS analysis, neutralization potentiometric titration, and SEM techniques. This new catalyst was used for preparation of 2-oxazolines and bis-oxazolines by reaction of β- ...
