Described herein is the first intermolecular sigma-bond exchange reaction between the C-C bond of cyclopropenones and C-Si bond of (benzo)silacyclobutanes and it proceeds smoothly by treatment with either 1mol% of a palladium or 2mol% of a nickel catalyst. This reaction constitutes an unprecedented route for the synthesis of various sila(benzo)suberones. And it is also the first example of a sigma-bond exchange reaction involving cyclopropenones.
