Chunjie Ni, Yining Zhao, Jin‐Ming Yang
Abstract
By using water as a solvent, an eco-friendly and practical protocol for the synthesis of furans and benzofurans through a Brønsted acid ionic liquid-catalyzed ring opening of 3,3-disubstituted oxetanes has been disclosed under mild conditions. This process shows broad substrate scope with good to excellent yields. More importantly, the BAIL catalyst can be easily recovered by simple separation and reused six times without significant loss of catalytic activity.
