Towards understanding monomer coordination in atom transfer radical polymerization: synthesis of [CuI(PMDETA)(π-M)][BPh4] (M = methyl acrylate, styrene, 1-octene, and methyl methacrylate) and structural studies by FT-IR and 1H NMR spectroscopy and X-ra

Four CuI complexes were isolated with coordinated monomers, [CuI(PMDETA)(π-M)][BPh4] (M = methyl acrylate, styrene, 1-octene, and methyl methacrylate). The CuI-olefin complexes were characterized by FT-IR spectroscopy and single crystal X-ray crystallographic analysis. The π-nature of the bonding was confirmed by 1H NMR spectroscopy.
