  1. Alkene complexes: Dewar-Chatt-Duncanson Bonding Model • Synergic Bonding • Both s-donation and p-acceptance weakens the CC bond Alkyne complexes: Dewar-Chatt-Duncanson Bonding Model Synergic Bonding All four possible bonding interactions weaken the CC bond Alkynes can be 2 or 4 electron donors, depending on whether the p┴ interaction is significant for a given complex

  2. Typical Ligands (Alkenes) - Alkene versus Metallacyclopropane Complex - Synthesis of Alkene Complexes

  3. Typical Ligands (Alkynes) - Alkyne versus Metallacyclopropene Complex Alkyne Coupling Connelly + Emslie, Dalton Trans, 2003, 2835
