33065-61-1 Usage
General Description
1H-Indene, 6-bromo- is a chemical compound with the molecular formula C9H7Br. It belongs to the class of organic compounds known as indenes, which are bicyclic compounds containing a six-member benzene ring fused to a five-member cyclopentadiene ring. As the name suggests, the compound contains a bromine atom attached to the 6th carbon atom of the indene ring. It is used in the production of various pharmaceuticals and agrochemicals, as well as in organic synthesis as a building block for the creation of more complex organic compounds. Additionally, 1H-Indene, 6-bromo- may also be used as a reagent in chemical reactions in research and industrial settings.
Check Digit Verification of cas no
The CAS Registry Mumber 33065-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,6 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33065-61:
(7*3)+(6*3)+(5*0)+(4*6)+(3*5)+(2*6)+(1*1)=91
91 % 10 = 1
So 33065-61-1 is a valid CAS Registry Number.

Selective alkylation and Suzuki coupling as an efficient strategy for introducing functional anchors to the ethylene-bis(indenyl) ligand
Panarello, Anthony P.,Vassylyev, Oleksiy,Khinast, Johannes G.

Chiral ansa-ethylene-bis(indenyl)-metal complexes, EBI-MX2, are useful pre-catalysts for a wide variety of reactions, including hydrogenations, hydrosilylations, and polymerization reactions. In order to immobilize these complexes onto heterogeneous supports, a new methodology was developed to introduce functional anchors to the ethylene-bis(indenyl) ligand, EBI. This was accomplished by selective alkylation of indene to form toluene-4-sulfonic acid 2-(3H-inden-1-yl)-ethyl ester, which was then used to alkylate 6-bromoindene. The selective introduction of an aryl bromide then undergoes coupling reactions with aryl borates via the Suzuki coupling to efficiently introduce an alkenyl or alcohol, functional anchor in a simple four step synthesis.
