Abstract

A rapid synthesis of aryl nonaflate was developed using 4-nitrophenyl triflate and 4- nitrophenyl nonaflate as perfluoroalkanesulfonyl transfer reagents in combination with a polymer supported base (PTBD). Simple filtration of the reaction mixture gave the desired products in high chemical yields and purity. The unique role of PTBD as a base and side product scavenger was demonstrated.
