Synthesis of acylsilanes via oxidative hydrolysis of 2-silyl-1,3-dithianes mediated by N-bromosuccinimide

The oxidative method for the hydrolysis of 1,3-dithianes was applied to 2-silyl-1,3-dithianes using N-bromosuccinimide providing acylsilanes with good yields under a short reaction period. The oxidation of aroylsilanes to carboxylic acid was prevented by the addition of bases and the lowering of the reaction temperature.
