Synthesis, Structures, and Reactivity of (R6-acen)ZrR'2 and (R6-acen)Zr(R')+ Complexes (R = H, F; R' = CH2CMe3, CH2Ph)

Dinuclear cationic zirconium complexes with the fulvalene ligand. Synthesis and reactivity

“…The compounds 2b, 3b, 8b and 9b have been spectroscopically characterized (see Experimental Section). Direct chloride abstractior~ processes from CHzCI~ -have been observed in other zirconium cationic systems to give chloride-bridged dinuclear cationic species [9].…”

A Lutetium Allyl Complex That Bears a Pyridyl‐Functionalized Cyclopentadienyl Ligand: Dual Catalysis on Highly Syndiospecific and cis‐1,4‐Selective (Co)Polymerizations of Styrene and Butadiene

“…[25] [Ph 3 C][BA C H T U N G T R E N N U N G (C 6 F 5 ) 4 ] was synthesized following the literature procedures. [26] X-ray crystallographic studies: Crystals for X-ray analysis were obtained as described in the preparations below. The crystals were manipulated in a glovebox.…”

Synthesis, Isolation and Structural Investigation of Schiff‐Base Alkoxytitanium Complexes: Steric Limitations of Ligand Coordination

“…[1][2][3][4][5] Much of this chemistry has focused on the development of new non-Cp ligands for alkyl d 0 metal compounds, which enhance α-olefin polymerisation, in the presence of co-catalysts, such as methylaluminoxane (MAO). A variety of ligands have been explored in recent years, including, for example, alkoxides and chelating alkoxides such as hydroxybenzaldehydes, [6][7][8][9]10] N 2 O 2 Schiff-base ligands, [11][12][13][14][15][16][17][18] and bidentate N,O ligands such as 8-quinolinolato and pyridine-alkoxides. [19][20][21][22] Much of this work has focused on the formation of complexes that incorporate bidentate ligands to af-3088 duced by this coordination mode.…”
