Catalytic Regioselective Introduction of Allyl Alcohol into the Nonpolar Polyolefins: Development of One-Pot Synthesis of Hydroxyl-Capped Polyolefins Mediated by a New Metallocene IF Catalyst
A new catalytic regioselective one-pot synthesis of hydroxyl-capped polyolefins is reported. This synthesis employs a new stereorigid bridged metallocene having an indenyl and a fluorenyl ligand named IF catalyst 1, exhibiting high catalytic performances. Here, we report on (1) the first example of...

| description | A new catalytic regioselective one-pot synthesis of hydroxyl-capped polyolefins is reported. This synthesis employs a new stereorigid bridged metallocene having an indenyl and a fluorenyl ligand named IF catalyst 1, exhibiting high catalytic performances. Here, we report on (1) the first example of allyl alcohol incorporation into the nonpolar polymer backbone using IF catalyst 1 and methylaluminoxane with high activity, high molecular weight, and high polar monomer uptake at high temperature, and (2) the first example of predominant end-site-selective introduction of an alcohol group into the polyolefins. Moreover, we observed the mixed regioselectivity by the type of alkylaluminum. |
