N-metallacycles from [Cp*MX2]2 and alkynylpyridines : synthesis, reaction pathway, and romaticity

The reaction of [Cp*MX2]2 (M = Rh or Ir, X = Cl, Br, or I) with alkynylpyridines afforded halogen-substituted N-metallacyclic complexes. The reaction pathway has been examined through deuterium labeling and other experiments and computational studies and is proposed to proceed via halide dissociatio...
