    • note
    • Aryl/heteroaryl nonaflates are generally more stable toward hydrolysis than the corresponding triflate and can easily be prepared from the corresponding phenol by reacting with perfluoro-1-butanesulfonyl fluoride. See ref 3a and the Supporting Information for more details.

    • note
    • DBU and MTBD are good microwave absorbers, which allows the reactions to attain higher temperatures faster in nonpolar solvents such as toluene.

    • note
    • When DBU was used as the base/solvent for more challenging substrate combinations, decomposition of the aryl nonflate predominated.
