925674-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 925674-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,6,7 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 925674-57:
(8*9)+(7*2)+(6*5)+(5*6)+(4*7)+(3*4)+(2*5)+(1*7)=203
203 % 10 = 3
So 925674-57-3 is a valid CAS Registry Number.

Direct C-H arylation of thiophenes at low catalyst loading of a phosphine-free bis(alkoxo)palladium complex

Li, Yabo,Wang, Jingran,Huang, Mengmeng,Wang, Zhiwei,Wu, Yusheng,Wu, Yangjie

, p. 2890 - 2897 (2014/05/06)

An efficient phosphine-free direct C-H arylation of thiophenes at the α-position has been developed at low catalyst loading of bis(alkoxo)palladium complex (Cat.I, 0.1-0.2 mol %). The developed synthetic method can be applied to the synthesis of α-aryl/heteroaryl thiophenes from aryl or heteroaryl bromides in good to excellent yields and is compatible with the substrates bearing electron-donating or electron-withdrawing groups. The reactivities of the 2- and 5-positions of thiophenes are equivalent and not dependent on steric hindrance under optimal conditions. This condition can also be applied to other heterocyclic moieties such as benzothiophene, benzofuran, and pyrrole with high conversion yields.

Pd-mediated C-H arylation of EDOT and synthesis of push-pull systems incorporating EDOT

Amaladass,Clement, J. Arul,Mohanakrishnan, Arasambattu K.

, p. 10363 - 10371 (2008/02/13)

The direct C-H arylation of 3,4-ethylenedioxythiophene (EDOT) is described under Heck-type experimental conditions. This methodology has been used to synthesize a series of push-pull systems containing EDOT units.
