Royer, Rene published the artcileReactioons induced by pyridine hydrochloride. IX. Possible uses of pyridine hydrochloride analogs for the dealkylation of phenolic ethers, COA of Formula: C10H14O, the publication is Bulletin de la Societe Chimique de France (1971), 4362-7, database is CAplus.
Pyridine hydrobromide (I) gave higher dealkylation yields of 2-alkoxynaphthalenes than pyridine hydrochloride (II), although temperatures >250° had to be used instead of ∼220°. The 2-naphthol yield from 2-isobutoxynaphthalene was 91% with I, compared with 11% for II. I also gave higher dealkylation yields of substituted anisoles, except those with large substituents next to the methoxy group. Thus for 2,6-diisopropylanisole demethylation was accompanied by isopropyl cleavage. PhNH2.HCl was less efficient than II as a dealkylating agent. 2,4-Lutidine hydrochloride was too sublimable to be used, but 3- and 4-picoline hydrochlorides were effective replacements for II. 2-Picoline retained too much H2O to be useful. Et2NH.HCl, BuNH2.HCl, and iso-BuNH2.HCl were less efficient dealkylating agents than II.
