Reaction Steps

Hexafluoroacetone (238 g) and 120 g of isobutylene were condensed into a lecture bottle using Dry Ice/2-propanol cooling. The temperature was raised in the sealed vessel to 20° C. while stirring in a water bath and temperature maintained overnight. The next morning the temperature was raised to 50° C. for 2 hours. After cooling, excess isobutylene was bled off and the product distilled at 100-115° C. to afford 264 g (83%) of a clear liquid. The identity of the product was confirmed using 1H NMR spectroscopy and HRMS.
