Zusammenfassung:Dodecylbenzenesulfonic acid (DBSA) was used as an efficient, cheap and stable Broensted catalyst for acetylation of alcohols and phenols and formylation of alcohols under solvent-free conditions. Various primary, secondary and tertiary alcohols were acetylated with acetic anhydride as an acetylating agent under solvent-free conditions in the presence of catalytic amount of DBSA at room temperature. Also, formylation of alcohols was catalyzed by DBSA with ethyl formate in high to excellent yields. This method showed high selectivity in acetylation and formylation of various alcohols and phenols. DBSA was recovered and reused in four successive runs without significant deterioration in catalytic activity.
