Abstract
O-alkyl-phenol-ethers are prepared by alkylation of phenolic hydroxy groups with a o-tri:alkyl-formic-acid-ester, either by: (a) o-alkylation of compounds containing phenolic hydroxy groups in a medium at pH: 5-11; or (b) via an iminium salt of formula [H2N=CHOAc]+Cl- (II) by a reaction with a 3.1 mole minimum excess of a 1-4C alcohol to yield an o-formic-acid-ester of formula CH(OR)3 (I). Resulting compound is used for o-alkylation at pH 5-11. Ac = inorganic or organic acid radical; R = 1-4C alkyl.
