Procedure

Example 1 was repeated using 2.27 g. (9 m mols) of diphenyldichlorosilane, 1.0 g. (8.6 m mols) of t-butylacetate and 0.07 g. of tetrabutylammonium bromide, except that the reaction mass was heated at 200° C. for 3 hours. A 48% conversion to t-butyl chloride and a 15% conversion to CH3COCl was obtained.
