title: Rhodium(I)-Catalyzed C-C Bond Activation of Siloxyvinylcyclopropanes with Diazoesters.
abstract: The rhodium(I)-catalyzed C-C bond activation reaction of siloxyvinylcyclopropanes with diazoesters demonstrates a novel mode of C-C bond cleavage of siloxyvinvylcyclopanes. The alkene products were obtained as single E-configured isomers in good yields. A σ,η3-allyl rhodium complex, which has been previously proposed as the key intermediate in rhodium(I)-catalyzed cycloaddition of vinylcyclopropanes, has been isolated and characterized by X-ray crystallography.
