CYCLOTRIMETHYLENEDIMETHYLSILANE Usage And Synthesis

Physical properties

bp 79–80 °C.

Uses

Reactive silicon compound capable of undergoing various insertion and ring-opening reactions.

Preparation

1,1-dichlorosilacyclobutane is treated with methylmagnesium halides or methyllithium in THF or Et2O. Exposure of chloro(3-chloropropyl)dimethylsilane to activated magnesium in THF or Et2O also gives the titled compound.
