Synthesis, Isolation, and Characterization of 1,1-DiGrignard and
1,1-Dizincio Silanes**

Geminal dimetallosilanes have already proved their great
potential for the synthesis of novel silicon compounds.[1]
However, the variety and number of isolated geminal
dimetallosilanes is very small.[13]
For example, all known
geminal dimetallosilanes are alkali metal or mercury deriv-
atives.[2]
Furthermore, only one example of a geminal
dimetallosilane with two different metals, that is, a mercury
bridged bis(silyllithium) species, was reported recently by our
research group.[1b,3]
This contrasts with the large variety of
available geminal dimetallorganic reagents, which are very
useful synthons in organic synthesis.[4]
