Abstract

The BIAN ligands in Brookhart catalysts were proved to be redox-active during the catalyst activation with alkylaluminum or MAO, and the neutral catalytically active species with a radical anionic BIAN rather than the cationic ones with a neutral BIAN ligand were confirmed to be formed in the catalytic system.
