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”.

quantitative and with -Markovnikov selectivity. The method is applicable to terminal alkenes, including those with O-, N- and halogen-containing functional groups, styrene and allylbenzene derivatives, etc., as well as to a wide range of alkyl-, phenyl-, siloxy- and alkoxy-containing tertiary hydrosilanes. These conditions turned out to be most efficient for hydrosilylation of gaseous reagents such as ethylene
