Application
Acyloin Condensation of Aliphatic Aldehydes Using Thiazolinium Ion Catalyst
Typical procedure:
A 500 mL, three-necked round-bottomed flask is charged with 3-Benzyl-5-(2-hydroxyethyl)-4-methylthiazolium Chloride (13.4 g, 0.05 mol), butyraldehyde (72.1 g, 1.0 mol), triethylamine (30.3 g, 0.3 mol), and absolute ethanol (300 mL). The mixture is stirred and heated at 80°C. After 1.5 h the reaction mixture is cooled to room temperature and concentrated by rotary evaporation. The residual yellow liquid is poured into 500 mL of water and extracted with 150 mL of dichloromethane. The aqueous layer is extracted with a second 150 mL portion of dichloromethane. The combined organic phases are washed with 300 mL of saturated sodium bicarbonate and with 300 mL of water. The dichloromethane is removed by rotary evaporation. Distillation through a 20 cm Vigreux column gives 51–54 g (71–74%) of product as a colorless to light-yellow liquid.
