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 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. Copyright © 2002 American Chemical Society.
