    • These analyses will be detailed in a subsequent publication. Even if the intermediate Rh-carbene complex is an equilibrating mixture of tetra-bridged and tribridged species (the latter analogous to 8) and even if the tribridged species is only a minor component of that equilibrium, the metallacyclobutane pathway (e.g., as in 9) proposed herein could still dominate kinetically.
