The preceding volume on The chemistry of organic silicon compounds (Vol. 2) in The Chemistry of Functional Groups series (Z. Rappoport and Y. Apeloig, Eds.) appeared in 1998. It followed an earlier volume with the same title (S. Patai and Z. Rappoport, Eds.) published in 1989 (now referred to as Vol. 1) and an update volume The silicon-heteroatom bond in 1991. The appearance of the present volume only three years after the three parts of Vol. 2 reflects the continuing rapid growth of many sub-fields of organosilicon compounds and their chemistry. 

In addition to protons, alkyl and acyl groups, silyl groups are sufficiently electropositive to initiate carbocationic polymerizations. Silicon is more electropositive than carbon, and therefore reacts with many nucleophiles, especially those based on oxygen. The resulting silicon-heteroatom bonds are relatively labile trimethylsilyl is thus often referred to as a bulky...

The reactivity of the newly synthesized anions was studied. As expected, they can easily be protonated and alkylated, in close analogy to other silyl anions we have investigated earlier [3, 4]. Furthermore, oligosilyl anions were successfully used for the formation of interesting silicon-heteroatom bonds [9]. In a similar manner, vinylsilyl potassium compound 4b can be transmetalated into the Mg analog [10], and the respective anion can then be used as a nucleophile in the reaction... 

Eq. 4. Functionalization of the anion provides easy access to new silicon-heteroatom bonds.
