ChemInform Abstract: Eco‐Efficient Synthesis of Cyclic Carbamates/Dithiocarbonimidates from Cyclic Carbonates/Trithiocarbonate and Aromatic Amines Catalyzed by Ionic Liquid BmimOAc.

Abstract

BmimOAc. -The reaction of cyclic carbonates with a variety of aromatic and heteroaromatic amines is advantageously achieved in [bmim]OAc as catalytic solvent to yield cyclic carbamates. The analogous cyclic trithiocarbamate (IX) yields 1,3-dithiolan--2-ylidene-arylamines under similar conditions. -(WANG, B.; YANG, S.; MIN, L.; GU, Y.; ZHANG, Y.; WU, X.; ZHANG, L.; ELAGEED, E. H.
