O-Acylation of Substituted Phenols with Various Alkanoyl Chlorides Under Phase-Transfer Catalyst Conditions
نویسندگان
چکیده
Esterification of several types of monoand disubstituted phenols with various monoand dialkanoyl chlorides was performed in phase-transfer catalysis conditions, using tetrabutylammonium chloride in a mixture of aqueous NaOH and dichloromethane. The process is particularly efficient (almost quantitative yields) as well as rapid (only 5 min reaction time, at a temperature of 0 C).

Potassium carbonate: a highly efficient catalyst for the acylation of alcohols, phenols and thiols under mild conditions
A general, mild and efficient protocol has been developed for the synthesis of esters and thioesters. The process has been taking place using tetra n-butylammonium iodide (TBAI) as a phase-transfer catalyst and in the presence of potassium carbonate (K2CO3). A wide range of esters and thioesters was prepared in high yields and suitable times by the treatment of alcohols, phenols and thiols with...

Sulfonamides amines, alcohols, and phenols were efficiently acylated with carboxylic acid anhydrides and chlorides using ZSM-5-SO3H as catalyst under mild and solvent-free conditions. Also, direct esterification of alcohols with carboxylic acids occurred readily in the presence of this catalyst. Different types of amides and esters were obtained in moderate to high yields and purity after a sim...
