Preparation of ortho-alkylated phenols |
摘要 |
Alkyl phenyl ethers may be induced to undergo thermal rearrangement on an alumina catalyst to afford the isomeric ortho-alkylphenol. Such rearrangement generally occurs under milder conditions than does the alkylation of a phenol with an olefin using the same alumina as an alkylating catalyst. Yields frequently are high with good selectivity.
