Coordinatively unsaturated Ru(II) species Ru(xantsil)(CO): A new active catalyst for oligomerization/deoligomerization of HSiMe2SiMe3 [xantsil = (9,9-dimethylxanthene-4,5-diyl)bis(dimethylsilyl)]. Isolation of a stabilized form of the silyl(silylene) intermediates

Ru(xantsil)(CO)(η6-C6H5CH3) (1) was found to be a catalyst for the oligomerization/deoligomerization of HSiMe2SiMe3 to give H(SiMe2)nMe (n = 1-8). A possible mechanism involving a silyl(silylene) intermediate was strongly supported by the isolation of its stabilized form, i.e., alkoxy-bridged bis(silylene) complex which was characterized by X-ray crystal structure analysis.
