Catalysis by metal complexes. VII. Hydrosilylation catalysed by tetrakis(ethylene)dichlorodirhodium(I)

Hydrosilylation catalysed by transition metal complexes coordinately bound to inorganic supports

“…From the results recorded in Table III it follows that in the addition to alkenes the activity of the catalysts decreases (with one exception) in dependence on the silicon hydride used in the order HSi(OC 2 H 5 ) 3 > HSi(C 2 H 5 }J > > HSiCI 3 . This is not unexpected as similar situation was already observed both with some soluble rhodium complexes 34 and with rhodium compounds bound to organic polymers 5 • 6 and was ascribed to differences in stability of respective silylrhodium complexes transiently formed in the course of the reaction (for detailed discussion see ref. 3 5 ).…”
