The disilane (Ph2HSi)2 reacted at room temperature with Co2(CO)8 to yield Co(SiPh3)(CO)4 as a major product. Corresponding monosilyl derivatives were formed also when other disilanes Ph3SiSiR2H (R2=Ph2, PhMe, Me2, Et2), Me3SiSiPh2H and PhMe2SiSiPhMeH were reacted with Co2(CO)8 under the same conditions. A mechanism based on silyl-silylene intermediates is proposed. The germylsilanes Ph3GeSiR2H (R=Ph, Et) with Co2(CO)8 also gave Co(SiPh3)(CO)4 by selective elimination of:GePh2 which was trapped by Co2(CO)8 as Ph2Ge[Co(CO)4]2. Crystal structures of Co(SiPh3)(CO)4 and Ph2Ge[Co(CO)4]2 are presented.
