A "Holy Grail" in olefin polymerization catalysis field is to discover transition metal catalysts that can efficiently copolymerize polar olefins. In a Communication to J. Amer. Chem. Soc. that is currently in press, Professor Guan and his graduate student Chris Popeney, and former postdoctoral fellow Drexel Camacho, have reported a cyclophane-based Pd(II) complex that is highly efficient in incorporating polar olefins like acrylates. Furthermore, low temperature NMR studies have revealed a unique mechanistic origin for the increased efficiency for polar olefin incorporation.
