摘      要：Summary of main observation and conclusion An intermolecular [4+2] cycloaddition was realized through C-C bond cleavage in the presence of Rh(Ⅰ) *** selective ring opening of 2-alkylenecyciobutanols enables the generation of active alkenylrhodium species,which underwent smooth cross addition over alkynes and (E)-2-nitroethenylbenzene,leading to highly substituted all-carbon six-membered rings in a single step and in a complete atom economy.
