EFFECT OF METAL IONS IN ORGANIC SYNTHESIS. XXXV SIMPLE AND CONVENIENT AROMATIC ALKYLATION OF SOME ALKENYLPHENOL DERIVATIVES WITH tert-ALKYL METHYL ETHERS IN THE PRESENCE OF TIN(IV) CHLORIDE
A very mild, simple and convenient method for the aromatic alkylation of some alkenylphenol derivatives with tert-alkyl methyl ethers to give sterically hindered phenols useful as antioxidants is reported.The reaction occurs with good yields at room temperature and is promoted by tin(IV) chloride.
