Applications

Dichlorodimethylsilane is used to prepare a resin bound siloxane with tertiary alcohols and it is also used as a reagent for synthesis of optically active ansa-mettallocene polymerization catalysts. It acts as a precursor to silicone and polysilane compounds. It is also used in the glass coating to protect it from micro particles. It is involved in the preparation of resin bound siloxane with reactivity towards tertiary alcohols.

Notes

Moisture sensitive. Store in a cool place. Incompatible with alcohols, amines and strong bases.

Literature References

Silicone intermediate and silylating agent, forming dimethylsilylene derivatives of diols. The main limitation of these is their extreme susceptibilty to hydrolysis. See Appendix 4.

For use in combination with triflic acid to generate dimethyldisilyl triflate, and its use in synthesis, see N,N'-Diacetyl­hydrazine, A13393 .
