Thioesters were efficiently prepared via the direct reaction of tertiary thioamides and alkyl halides in water, and in the presence of catalytic amounts of NaI, hexadecyltrimethylammonium bromide (HTAB), and 1,4-diazabicyclo[2.2.2] octane (DABCO). Hence,

A one-pot synthesis of thioesters directly from carboxylic acids, N,N′-diphenylthiourea, triethylamine, and primary alkyl halides is described. Microwave-assisted heating and a catalytic amount of 4- (dimethylamino)pyridine (DMAP) further improved the yields. Both aromatic and aliphatic carboxylic acids were converted to the corresponding thioesters, and many functional groups were compatible with this reaction. Several possible reaction intermediates were investigated, and the quaternary ammonium salts, derived from alkyl halides and tertiary amines, were the intermediates to yield thioesters. A new reaction mechanism for this thioesterification is proposed.

Diverse thioesters were efficiently prepared via the solvent-free reaction of thioamide derivatives with alkyl halides in the presence of catalytic amounts of 1,4-diazabicyclo[2.2.2]octane (DABCO) in small quantities of water and in good to excellent yiel

supporting information; experimental part, p. 2861 - 2866 (2011/02/16)
A one-step conversion of alcohols into thioesters under solvent-free conditions is reported. The alcohols were reacted with primary thioamides in the presence of p-toluenesulfonic acid under solvent-free conditions to produce the corresponding thioesters in good to excellent yields.
