Synthesis, structure, and reactivity of hydridobis(silylene)ruthenium(IV)- xantsil complexes (xantsil = (9,9-dimethylxanthene-4,5-diyl)bis(dimethylsilyl)) - A stabilized form of key intermediates in the catalytic oligomerization- deoligomerization of hydrosilanes

Ru {K2(Si,Si)-xantsil}(CO)(η6-C6H 5CH3) (1) was found to be a catalyst for oligomerization-deoligomerization of HSiMe2SiMe3 to give H(SiMe2)nMe (n = 1-8 at 90°C for 2 days). Treatment of 1 with HSiMe2SiMe2OR (R = Me, f-Bu) led to quantitative formation of Ru{κ3(O,Si,Si)-xantsil}(CO)(H) {(SiMe2...O(R)...SiMe2)} (R = Me (2a), t-Bu (2b)), which also worked as a catalyst for oligomerization-deoligomerization of HSiMe2SiMe3. Based on these experimental results, a mechanism involving silyl(silylene) intermediates was proposed for the oligomerization-deoligomerization of HSiMe2SiMe3. Complex 2a reacted with MeOH in toluene-d8 to give Ru{κ 2(Si,Si)-xantsil}(CO)(η6-toluene-d8) and Me2Si(OMe)2 with evolution of H2. Under a CO atmosphere, 2a was smoothly converted to its CO adduct Ru{κ 2(Si-Si)-xantsil}(CO)2(H){(SiMe2...O(Me) ...SiMe2)} (3).
