Synthesis, characterization, and catalytic activity of a well-defined rhodium siloxide complex immobilized on silica
(Chemical Equation Presented) Rhodium siloxide surface complex 2, which was obtained directly by reaction of molecular precursor 1 with aerosil silica and characterized inter alia by solid-state NMR spectroscopy, is a highly active and stable catalyst for hydrosilylation reactions.

Hydrosilylation of functionalised olefins catalysed by rhodium siloxide complexes in ionic liquids
The use of ionic liquids for the immobilization of rhodium siloxide complexes has permitted development of highly effective catalysts for the hydrosilylation processes. Herein, we report the synthesis of organosilicon compounds in a biphasic reaction setup, allowing separation of the product, recovery and reuse of the catalyst, which is fundamental from the point of view of "green chemistry".
