General Description

Cyclopentadienylindenylzirconium dichloride, also known as Cp2Zr(η5-C9H7)Cl2, is an organometallic compound used as a catalyst in various chemical reactions, particularly in polymerization processes. Cyclopentadienylindenylzirconium dichloride features a zirconium atom coordinated with two cyclopentadienyl and one indenyl ligand, as well as two chloride ions. It has been employed in the synthesis of various materials, including polyolefins and elastomers, due to its ability to initiate and control polymerization reactions. Cp2Zr(η5-C9H7)Cl2 is known for its high reactivity and selectivity in catalyzing olefin polymerization, making it a valuable tool in the production of a wide range of commercial polymers.

Check Digit Verification of cas no

The CAS Registry Mumber 80155-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80155-52:
(7*8)+(6*0)+(5*1)+(4*5)+(3*5)+(2*5)+(1*2)=108
108 % 10 = 8
So 80155-52-8 is a valid CAS Registry Number.

Schmid, Michael A.,Alt, Helmut G.,Milius, Wolfgang

, p. 45 - 49 (1996)

The reaction of indenyllithium, IndLi, with CpMCl3 (M = Ti, Zr) or Cp*MCl3 (M = Zr, Hf) leads to complexes of the type (L)(Ind)MCl2 (1: L = Cp, M = Ti; 2: L = Cp, M = Zr; 3: L = Cp*, M = Zr; 4: L = Cp*, M = Hf). In combination with methylaluminoxan (MAO), complexes 1-4 show a high catalytic activity as homogeneous ethylene polymerization catalysts. The ethylene selective catalyst precursor 3 was characterized by an X-ray structure analysis.

Synthesis of racemic chiral-at-metal complexes of the Group 4 metals

Alcock, Nathaniel W.,Clase, Howard J.,Duncalf, David J.,Hart, Suzanne L.,McCamley, Andrew,McCormack, Peter J.,Taylor, Paul C.

, p. 45 - 54 (2007/10/03)

A protocol for asymmetric synthesis of chiral-at-metal complexes is described, but enantiomerically-enriched products can not be isolated due to formation of complexes between the Group 4 metallocene products and the borane by-products. An efficient method for synthesis of racemic chiral-at-metal metallocenes, through lithium chloride catalysed ligand redistribution reactions, is described. Sterically-hindered racemic chiral-at-metal complexes are prepared by nucleophilic substitution of prochiral dichlorides.
