General description

Dichlorodimethylsilane is an organosilicon compound generally used as a protecting group for diols and carbonyl compounds. It is also used as a starting material for the preparation of silicon-based reagents.

Application

Dichlorodimethylsilane can be used:
  • As a silane coupling agent in the synthesis of silica nanoparticles and in their surface modification studies.
  • To prepare polydimethylsiloxane microemulsions by reacting with sodium dodecylpolyoxyethylene sulfate.
  • To prepare a novel heterasumanene where the benzylic carbon atoms of the sumanene are replaced by heteroatom (S, Si) functionalities
