摘要

High throughput screening (HTS) of a 205 member Schiff base salicylaldimine ligand library derived from salicylaldehydes bearing bulky ortho-substituents, ie, 9-anthracenyl, 1, 4, 5, 8- tetramethylanthracenyl or triptycenyl, reacted in-situ with (p-tolyl) CrCl2 (thf) 3, identified two new classes of highly active chromium based systems for the oligomerization and polymerization of ethylene, respectively. The polymerization system comprises bidentate ...
