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‐alkoxy‐silacyclohex‐3‐enes 5. Catalytic hydrogenation of compound 3 affords silacyclohexane 4. The new heterocycles are characterized by 13 C and 1 H NMR, as well as mass spectroscopic data. © 1999 John Wiley & Sons, Inc.
