Participants

Reaction Steps

2-Butyl-4-oxocyclohex-2-ene carboxylic acid ethyl ester (9.05 g; 40 mmole), ethyleneglycol (2.73 g; 44 mmole) and p-toluenesulphonic acid (100 mg) were refluxed in benzene (80 ml) using a Dean-Stark water trap. After 12 hours the mixture was cooled, diluted with diethyl ether and washed with saturated aqueous sodium bicarbonate followed by water. Drying over MgSO4 and evaporation gave a liquid (10.80 g 100%) which was pure enough to use directly. Found: C,66.71; H,9.79, C15H26O4 requires C,66.64; H,9.69%.
