Metal hydrido complexes with silanes

The published chemistry of group 8 metal PSiP complexes is thus far restricted to the synthesis of Ru" complexes. PSiP complexes of Ru" were first reported by Stobart and coworkers, who studied the complexation of the bis(phosphinoalkyl) silanes 1 and 5 with Ru carbonyl species. In an initial study, low yields of the 18-electron hydrido carbonyl complexes [K -(Ph2P(CH2)n)2SiMe]Ru(H)(CO)2 (17, n = 2 18, =3) were obtained upon reaction of either 1 or 5 with RUjICOljj (Scheme 6.5) [36]. Complex 18 was crystallographically characterized and featured... 

Isomerization of olefins which takes place as a result of the transfer of hydrogen atoms with concomitant migration of the double bond is catalyzed by transition metal complexes which may react with olefins to form organometallic compounds. Often, it is necessary that cocatalysts be present as sources of hydrogen. Most commonly utilized cocatalysts are acids, water, alcohol, hydrogen, silanes, etc. The formation of hydrido complexes during isomerization reactions is crucial. The following mechanisms of olefin isomerization reactions are known ...
