Chlorosilanes are the most important functional silicon compounds. As described above, chlorosilanes can be used for silicon—carbon and silicon—silicon bond formation. In addition, chlorosilanes can be converted into other functional silicon compounds, such as hydrosilanes, alkoxysilanes, and aminosi-lanes. Hydrosilanes, alkoxysilanes, and aminosilanes can be transformed furthermore into other functional silicon compounds. Combination of functional group transformation and silicon-carbon and silicon—silicon bond formation of chlorosilanes are essential for the construction of organosilicon clusters. 

Deaminochlorination is a useM method of transforming aminosilanes to chlorosilanes. Deaminochlorination is carried out by treatment of aminosilanes with hydrogen chloride or acetyl chloride (37—39). The sequence of amination of chlorosilane, appropriate transformation, and deaminochlorination shovra that amino groups can be used as protecting groups for chlorosilanes. This elegant method of protection and deprotection was established by Tamao (40).
