    • The 19F NMR resonances of 1-5 in benzene-d6 varied in appearance, ranging from broad, unresolved singlets to well-resolved quartets. We thank an anonymous reviewer, who suggested that the broadening may arise from hydrogen bonding to adventitious water or HF and that addition of dry CsF can scavenge such impurities. Indeed, we find that, upon addition of CsF to samples of 2 and 3, broad 19F resonances are sharpened to quartets, allowing JFP coupling constants of 23.0 Hz to be determined in both cases
