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,η 3 ‐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.
