The trimethylsilylethylbenzenes have been prepared and the oxidation of these silanes with oxygen has been studied Thk oxidation, carried out at 200-220" in the presence of chromic oxide and calcium carbonate, has given moderate yields of 0-, m-and p- trimethylsilylacetophenone as well as the corresponding trimethylsilylbenzoic acids. The resulting new organosilanes have been characterized and derivatives have been ...
