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. |
