Silabicyclo[3.1.0]hexane 2 obtained from silacyclopent-3-ene 1 by dichlorocarbene addition is useful in the synthesis of ring-expanded products, such as silacyclohexa-2,4-diene 3 and 5-alkoxysilacyclohex-3-enes 5. Catalytic hydrogenation of compound 3 affords silacyclohexane 4. The new heterocycles are characterized by 13C and 1H NMR, as well as mass spectroscopic data.
