The relative reactivities of Zn, Al, and Sm carbenoids in the chemoselective carbene insertion reaction of heavier group 14 hydrides were studied. By variation of the reaction protocols using Sm carbenoids, insertion reaction can favour the Ge-H bonds to give Ge-alkylated derivatives in good to high yield.
Preparation of ethylene-bridged Group 14 metal-zirconocene complexes

, p. 299 - 303 (2007/10/03)
The reactions of the zirconocene-ethylene complex Cp2Zr(CH2=CH2)(PMe3) with Group 14 metal chlorides or alkoxides give ethylene-bridged group 14 metal-zirconocene complexes. A reaction mechanism via a five-membered intermediate which involves direct coupling of ethylene and single bonding is proposed.
METHYLPHENYLTRIPHENYLGERMYLSILANES FONCTIONNELS OPTIQUEMENT ACTIFS. II. REACTIONS DE CLIVAGE DE LA LIAISON Si-Ge
Corriu, R. J. P.,Ould-Kada, S.,Lanneau, G. F.
, p. 39 - 50 (2007/10/02)
The cleavage of a silicon-germanium bond in the presence of organometallics has been studied on the optically active compounds MePh(X)SiGePh3 (X=H, OMe).Depending on the nature of the nucleophile, we obtained mixed products, corresponding to the formation of Ph3Ge-, transient radical-anions, or catalytic reactions.
THE CHEMICAL BEHAVIOUR OF COBALT-STABILIZED-CARBENES HAVING A TRISUBSTITUTED SILYL OR GERMYL LIGAND. STEREOSPECIFIC FORMATION OF BENZOYLSILANES FROM THE REACTION OF ORGANOSILYL-COBALT TETRACARBONYL DERIVATIVES WITH PHENYLLITHIUM
Cerveau, Genevieve,Colomer, Ernesto,Corriu, Robert J.P.,Young, J. Colin
, p. 31 - 45 (2007/10/02)
We report the chemical behaviour of cobalt-stabilized carbenes, R3M(CO)3CoC(OEt)R', and their parent anions, R3M(CO)3CoC(O-)R', where M = Si or Ge.The anions where M = Si, R' = Ph decompose thermally into the corresponding benzoylsilanes; when the silicon atom is chiral (R3 = MePh-1-Np) optically active R3SiCOPh is obtained with complete retention of configuration.
