•Unmodified fluorous silica gel (FSG) was discovered as an efficient catalyst in Fries rearrangement.•A reusable fluorous catalyst system with the advantages of being commercially available was employed.•Ease of work-up, high recovery, low cost of procedure, and simplicity were the other advantages.
Commercially available fluorous silica gel (Fluoro Flash™) with no further post-modification was successfully investigated and applied merely as a catalyst in Fries rearrangement of various aryl esters under solvent free conditions in 4 h and optimized temperatures. In addition to good yields and recyclability of the catalyst, toxicity of reaction medium, by-products, and wastes were minimized. Also, low catalyst loading was another advantage of this methodology.
