Abstract
The alkylation of aromatic substrates with methanal has been studied o n potassium substituted salts of 12-phosphotungstic acid. Substitution at ring positions appears to be the predominant route. Among the pota ssium substituted salts, the salt containing K-2.5 is the most active probably because of higher strength of Bronsted acid sites on this sys tem. Mechanistic details of this reaction are discussed.
