In the 1st part of this presentation, organometallic catalysis for polyolefin synthesis via coordination polymerization will be discussed. To develop a novel titanocene catalyst for efficient ethylene-styrene (ES) copolymerization at high temperature, which is compatible with most commercial processes, titancenes containing a pendant amine donor were prepared and their catalytic activities were investigated for the copolymerization of ethylene and styrene at 120 °C. In the 2nd part of the talk, selective oligomerization of ethylene to 1-hexene or 1-octene will be discussed, focusing on the intermediacy of metallacycles that could provide an opportunity to generate new classes of functionalized ethylene oligomers by chain transfer to a transmetalation reagent. |
