The reaction of dicarbonyl compounds with potassium in the presence of trimethylsilyl chloride was studied. The carbonyl compounds were benzil (II), 9,10-phenanthroquinone (III), <I>p</I>-benzoquinone (IV), disodium salt of tetrahydroxy-<I>p</I>-benzoquinone (V), and <I>trans</I>-dibenzoylethylene (VI), as well as benzophenone (I). I and II gave bistrimethylsiloxy compounds in good yields, but III did not react under the same conditions. 1,4-Bistrimethylsiloxybenzene and 1,4-diphenyl-1,4-bistrimethylsiloxybutadiene were obtained from IV and VI respectively. A similar conjugate reductive silylation was successful with V affording hexakistrimethylsiloxybenzene in 35% yield.
