摘要：

o-Bis(dimethylsilyl)benzene (1) reacts with cyclopentadienylbis(ethylene)cobalt at room This reaction results in overall double Si-H activation, generating the disilacobaltacycle complex Cp(C2H4)Co(o-Me2SiC6H4SiMe2) (3). Complex 3 was characterized by X-ray diffraction. 1,2,4,5-Tetrakis(dimethylsilyl)benzene reacts with CpCo(C2H4)(2) to give 4,12,6,10-benzo-1,1,3,3,7,7,8,9,9-nonamethyl-1,3-disilacobaltacycle-7,8-disilacyclopent-6-ene (4). Complex 4 was characterized by X-ray diffraction and found to contain a 6,10-benzo-7,7,8,9,9-pentamethyl-7,9-disilacyclopent-6-ene via 1,1-double silylation.
