Utilizing neutral and anionic bis(pyrazolyl)methane (Bpm) based ligands as supporting ligands, we have performed a systematic study on the alkene/alkyne-metal interaction in cationic and neutral complexes of group 11 "coinage" metals (Cu(I), Ag(I), Au(I)) with alkenes and alkynes of varying length. We have used electron donating methyl substituted Bpm and highly fluorinated electron withdrawing trifluoromethyl substituted Bpm ligands to probe the effect of changing the ligand nature has on the metal-ethylene interaction. Utilizing NMR, vibrational spectroscopy, and XRD we have investigated the effects that changing the supporting ligand, net charge, metal, and olefin/alkyne has on the structure and bonding of the metal-olefin complex.
