Abstract
When an organoxysilyl or siloxy-containing ethylnorbornene compound is prepared by hydrosilylation of 5-vinyl-2-norbornene with a hydrogen organoxysilane or siloxy compound in the presence of a platinum catalyst, hydrosilylation is conducted in the co-presence of an ammonium salt. The organoxysilyl or siloxy-containing ethylnorbornene compound is effectively prepared at high reactivity and selectivity.
