Rings of gold: Vinylidenecyclopropanes can undergo efficient oxidative ring enlargements under mild conditions to give the corresponding alkylidenecyclobutanone derivatives in good yields (see scheme). A plausible mechanism for this transformation has bee
A catalytic method for the preparation of polysubstituted cyclopentanes: [3+2] cycloaddition of vinylidenecyclopropanes with activated olefins catalyzed by triflic imide
