Abstract
The n.m.r. spectra of phenol, anisole, and other phenols and aromatic ethers in solution in fluorosulphuric acid and in 70% perchloric acid show that in every case they protonate on an aromatic carbon. Earlier evidence from ultraviolet spectroscopy that phenol and anisole protonate on oxygen is reinterpreted.Keywords
