Procedure

1-(Trifluoromethyl)ethenyl acetate (Aldrich, 188.0 grams, 1.22 mole), trichlorosilane (80.6 grams, 0.60 mole), and 200 ml heptane were placed in a round bottom flask equipped with a water condenser and nitrogen inlet. Platinum(O)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex in xylene (10 ml) was added to this solution and heated to reflux for 18 hours. Afterwards, the solution was cooled to room temperature and additional portions of trichlorosilane (80.6 grams, 0.60 mole) and platinum complex (5 ml) were added and heated to reflux for 48 hours. Proton NMR of the solution indicated about 75% conversion. A third portion of trichlorosilane (67.7 grams, 0.50 mole) and platinum complex (5 ml) were then added and the solution heated to reflux for 48 hours. Solvents were distilled off at atmospheric pressure and the residue was fractionally distilled under reduced pressure. 2-Acetoxy-3,3,3-trifluoropropyltrichlorosilane (251.7 grams) (1.A) was collected between 100-125° C. at 20 mm pressure as a clear liquid.
