Potassium Hydroxide → HCID 54158494, compound

Participants

Reaction Steps

To a stirred mixture cooled at 10° C. of 10 g of demineralized water, 17.3 g of a 45% by weight-potassium hydroxide solution in water (0.139 moles) and 12.9 g of 2-methyl-3-buten-2-yl hydroperoxide (0.120 moles) there were added over a period of 25 minutes 14.5 g of pivaloyl chloride (0.120 moles); the temperature of the reaction mixture was kept at 10°-12° C. Stirring was continued for 1 hour, after which the organic layer was isolated. It was washed successively with an aqueous solution of 10% by weight-KOH (15 min, 10° C.), an aqueous bisulphite/acetate buffer (20 min., 10° C.) and a dilute solution of sodium bicarbonate in water (2x). Finally, the organic layer was dried with MgSO4 and the product was isolated by filtration. There were obtained 17.3 g of colourless oil containing 97.7% of peroxy ester, which corresponds to a yield of 75.6%. The identity of the product was confirmed by IR and NMR spectroscopy (1H and 13C).
