Synthesis and characterization of bis(indenyl) zirconium aryloxide derivatives and their use in α‐olefin polymerization

Abstract

BuC 6 H 4 , 6) were synthesized by a metathesis reaction of Ind 2 ZrCl 2 (1) with the appropriate thallium aryloxide salt, TlOL. The complexes 1-6 were characterized by 1 H and 13 C NMR techniques. They were also examined as catalysts for ethene and 1-hexene polymerization with methylalumoxane as co-catalyst, and a trend of the polymerization activity as a function of aryloxide ligands was observed. An interpretation of this trend, considering both the electronic and steric effects of the substituents on the aryloxide rings, was proposed.

Homoleptic Cobalt and Copper Phenolate A2[M(OAr)4] Compounds: The Effect of Phenoxide Fluorination

“…Tl(OAr F ). This compound also previously has been reported in the literature − as a reagent, and we report the synthesis and spectroscopic data that characterize this material here for the same reasons as for K(OAr F ). A 25-g portion of TlOEt (100.23 mmol) was added via syringe to 18.45 g of HOAr F (100.23 mmol) in 500 mL of CH 2 Cl 2 with vigorous stirring.…”
