Selective cleavage of benzyl and p ‐methoxybenzyl (anisyl) ethers is permitted by the new range of radical cations of polybrominated triarylamines having various oxidation potentials. One application is the synthesis of (2) from (1) ; this reaction requires selective protection of the two OH groups and selective deprotection.
