When diethyl tellurium was heated with triorgano silanes, germanes, or stannanes, one or both tellurium-carbon bonds were cleaved and compounds with tellurium-group IV element bonds were formed3 4. 

Mg Si bonds have long been inferred in reactions that generate hexaorganodisilanes from halo(triorgano)silanes and either a Grignard reagent or Mg metal ( Silico-Barbier reaction). Similarly, the electrochemical reduction of chloro(triorgano)silanes with sacrificial Mg electrodes yields...

Recently, Schaumann et al. 153,154 an(j Bienz et tf/.155,156 have developed dependable routes for the resolution of racemic functionalized organosilanes with Si-centered chirality using chiral auxiliaries, such as binaphthol (BINOL), 2-aminobutanol, and phenylethane-l,2-diol (Scheme 2). For instance, the successive reaction of BINOL with butyllithium and the chiral triorganochlorosilanes RPhMeSiCl (R = /-Pr, -Bu, /-Bu) affords the BINOL monosilyl ethers 9-11, which can be resolved into the pure enantiomers (A)-9-ll and (7 )-9-11, respectively. Reduction with LiAlFF produces the enantiomerically pure triorgano-H-silanes (A)- and (R)-RPhMeSiH (12, R = /-Pr 13, -Bu 14, /-Bu), respectively (Scheme 2). Tamao et al. have used chiral amines to prepare optically active organosilanes.157...
