Poly(3,4-dimethyl-5-vinylthiazolium)/DBU-catalyzed thioesterification of aldehydes with thiols

Poly(3,4-dimethyl-5-vinylthiazolium) was synthesized from 3,4-dimethyl-5-vinylthiazole through free radical polymerization and was examined as polymer precatalysts in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) for the thioesterification of aldehydes with thiols. The poly(5-vinylthiazolium)/DBU had excellent catalytic activity and could be reused 10 times without a considerable loss of activity. To S-um up: Poly(3,4-dimethyl-5-vinylthiazolium) is examined as a polymer precatalyst in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) for the thioesterification of aldehydes with thiols. The poly(5-vinylthiazolium)/DBU system shows excellent catalytic activity and can be reused 10 times without a considerable loss of activity.

A simple and convenient method for preparation of carboxylic acid alkyl esters, phenolic and thioesters using chlorodiphenylphosphine/I2 and imidazole reagent system

Condensation of carboxylic acids with alcohols, phenols and thiols proceeded smoothly to afford carboxylic acid alkyl esters, phenolic esters and thioesters by using the combination of chlorodiphenylphosphine, imidazole and molecular iodine in refluxing acetonitrile. Esterification with this mixed reagent system gave the corresponding products in excellent yields. The phosphorus-containing byproduct was simply removed from the organic phase by basic aqueous workup without the need for chromatography purification.
