Abstract
An intramolecular cycloisomerization occurred upon, adding a tertiary amine N-oxide to alkyne-cobalt complexes, derived from 3-sila 1,7-enyn es and dicobalt octacarbonyl. As a result, eight-membered cyclic dieny lsilanes were obtained by a regioselective insertion of the alkynyl gr oup into the C(1)-H bond.
