It has been established that a Rh I+ /segphos complex catalyzes the [2+2+1] cycloaddition of 1,6‐diynes with cyclopropylideneacetamides to give substituted fulvenes in good yields. The reductive complexation of the product fulvenes with RhCl 3 in EtOH furnished the corresponding dinuclear cyclopentadienyl Rh III complexes bearing a pendant amide moiety. These Rh III complexes were highly active catalysts for oxidative annulation and cyclization through C(sp 2 )−H and C(sp 3 )−H functionalization.
