Carbonyl molybdenum and tungsten oxadiene complexes exhibit high catalytic activity in hydrosilylation of unsaturated ketones and aldehydes, even those geometrically fixed in s-trans-arrangement, using PhSiH3 and Ph2SiH2. In the case of 4-phenylbut-3-en-2-one as substrate, variable chemoselectivity is observed depending on the specific catalyst employed.
