Oligo(phenylcobaltcarbonylsilane) was prepared from oligo(phenylsilane) and dicobalt octacarbonyl. The reaction proceeds with elimination of Hj and CO and insertion of cobalt carbonyl fragments into the silicone backbone of oligosilane. Oligosilane containing cobalt carbonyl groups in side organic substituents was obtained from oligo[methyl(phenylethynyl))si!ane and CojfCOJg. The reaction of l,2-bis(phenylethynyl)tetramethyldisilane with Co2(CO)g proceeds with the sequential attachment of cobalt carbonyl fragments to ethynyl groups to form disilane derivatives [n2-C=CPhCo2(CO>6|. Thermal decomposition of cobalt-containing oligosilanes affords a mixture of paramagnets and ferromagnets.
