Abstract Replacing dipolar and aprotic solvents with environmentally benign media has emerged as a new facet of green chemistry. In this paper, sulfone‐containing imidazolium‐based Brønsted acid ionic liquid was prepared used recyclable catalyst. The catalyst enables the use an industrially acceptable solvent, butyl acetate, reaction medium. liquid/butyl acetate biphasic system successfully utilized in many organic reactions, which generally relied heavily on solvents. magnified image
