Versuchsvorschrift

The above methyl ether, 48.5 g (0.209 mol), and 1 g of AlCl3 were refluxed together for 15 hours and treated as described in Comparative Example 1. An amount of 43.8 g of unreacted (CF3)2CHCF2OCH3 was recovered, together with 1.1 g of (CF3)2CHCOF (2.7% yield) and 0.75 g of CH3F. No improvement in product was obtained when the reactants were heated in a sealed tube at 120° for 4 hours.
