C12Si=CHCH2tBu is a versatile building block in organosilicon synthesis which reacts with a wide variety of multiple bond systems. The unique reactivity is shown by the predominance of [2+2] over [4+2] cycloaddition reactions. This unusual behaviour is caused by the two chlorine substituents at the silicon atom. This presentation shows the synthesis of silacyclobutenes from Cl2Si=CHCH2tBu and disubstituted alkynes and some chemistry of these four membered ring compounds.
