Industrially Important Organo-Silicon Compounds, Nomenclature

1 Industrially Important Organo-Silicon Compounds, Nomenclature 

Industrially produced organo-silicon compounds include monomeric low molecular compounds, almost exclusively belonging to the class of silanes, and oligomers and polymeric compounds including oligomeric silanes, polysilanes, oligomeric silazanes, polysilazanes and particularly oligomeric siloxanes and polysiloxanes (silicones). 

Specific lUPAC nomenclature for organo-silicon compounds has not yet been developed. According to general lUPAC rules, the tetravalent compounds should be known as silanes and their ligands should be listed in alphabetical order and hydrogen should not be mentioned. 

In the technical literature the ligands are listed in the order organo-functional-, non-functional- and silicon-functional-ligands. The term organofunctional ligand means a unit containing a functional group linked to a carbon atom (e.g. -Cl, -NH2, -C=C-). 

So-called silicon-functional ligands are silicon atom-linked ligands which can be easily substituted (e.g. Si-Cl, Si-OR).
