Abstract
Silyl substituents stabilize ketenes, and permit the preparation of pe rsistent bisketenes, which show characteristic C-13, O-17, and Si-29 N MR chemical shifts. The structures and conformations of bisketenes hav e been examined, as well as their interconversion with cyclobutenedion es. A tetraketene has been prepared, and the hydration reactivity of c arbon suboxide has been measured.
