2,5-BIS(HEXYL)-1,4-DIBROMOBENZENE, also known as 1,4-dibromo-2,5-di-n-hexylbenzene or 1,4-dibromo-2,5-dihexylbenzene, is a key intermediate used in the synthesis of monodisperse oligo(phenyleneethynylene)s (oligoPPEs). It serves as a building block in Pd-catalyzed alkyne-aryl coupling reactions, contributing to the iterative convergent/divergent synthesis strategy for constructing these oligomers. 2,5-BIS(HEXYL)-1,4-DIBROMOBENZENE's bromine substituents enable further functionalization, such as halogen-metal exchange and coupling reactions, facilitating the efficient production of gram-scale oligoPPEs with potential applications in nanoscopic architectures.

117635-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 117635-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,3 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117635-21:
(8*1)+(7*1)+(6*7)+(5*6)+(4*3)+(3*5)+(2*2)+(1*1)=119
119 % 10 = 9
So 117635-21-9 is a valid CAS Registry Number.

A new family of biisoquinoline chelates

Durola, Fabien,Hanss, David,Roesel, Pirmin,Sauvage, Jean-Pierre,Wenger, Oliver S.

, p. 125 - 135 (2007/10/03)

Four 8,8′-diaryl-substituted 3,3′-biisoquinoline ligands have been synthesized and characterized. The key feature of this new family of chelates is their endotopic but sterically non-hindering nature. All four ligands were made from a common 8-bromoisoquinolin-3-ol precursor; between three and twelve synthetic steps were necessary to obtain the products. The reported synthetic procedures allow for gram-scale production of these biisoquinolines. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Conjugated Organometallic Polymers Containing Vollhardt's Cyclobutadiene Complex: Aggregation and Morphologies

Steffen, Winfried,Koehler, Bernhard,Altmaim, Markus,Scherf, Ullrich,Stitzer, Katherine,Loye, Hans-Conrad zur,Bunz, Uwe H. F.

, p. 117 - 126 (2007/10/03)

Organometallic polymers were prepared by acyclic diyne metathesis (ADIMET) or by Pd-catalyzed coupling of 1,3-diethynylcyclobutadiene(cyclopentadienyl)cobalt with a suitably substituted diiodobenzene. The polymers obtained by Heck coupling show a degree o

A High-Yield Route to 2,5-Di-n-alkyl-1,4-benzenedicarboxylic Acids

Rehahn, Matthias,Schlueter, Arnulf-Dieter,Feast, W. James

, p. 386 - 388 (2007/10/02)

A simple and inexpensive method for preparing the previously unknown 2,5-di-n-alkylterephthalic acids 5a-d in high yields is presented.The length of the alkyl chains can be varied easily (n=6,8,12,16).
