852106-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 852106-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,1,0 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 852106-25:
(8*8)+(7*5)+(6*2)+(5*1)+(4*0)+(3*6)+(2*2)+(1*5)=143
143 % 10 = 3
So 852106-25-3 is a valid CAS Registry Number.

Electrochemical Synthesis of Biaryls via Oxidative Intramolecular Coupling of Tetra(hetero)arylborates

Music, Arif,Baumann, Andreas N.,Spie?, Philipp,Plantefol, Allan,Jagau, Thomas C.,Didier, Dorian

supporting information, p. 4341 - 4348 (2020/03/04)

We report herein versatile, transition metal-free and additive-free (hetero)aryl-aryl coupling reactions promoted by the oxidative electrocoupling of unsymmetrical tetra(hetero)arylborates (TABs) prepared from ligand-exchange reactions on potassium trifluoroarylborates. Exploiting the power of electrochemical oxidations, this method complements the existing organoboron toolbox. We demonstrate the broad scope, scalability, and robustness of this unconventional catalyst-free transformation, leading to functionalized biaryls and ultimately furnishing drug-like small molecules, as well as late stage derivatization of natural compounds. In addition, the observed selectivity of the oxidative coupling reaction is related to the electronic structure of the TABs through quantum-chemical calculations and experimental investigations.

1,4-Difluoro-2,5-dimethoxybenzene as a precursor for iterative double benzyne-furan Diels-Alder reactions

Morton, Gillian E.,Barrett, Anthony G. M.

, p. 3525 - 3529 (2007/10/03)

(Chemical Equation Presented) The use of 1,4-difluoro-2,5-dimethoxybenzene as a novel precursor for iterative two-directional benzyne-furan Diels-Alder reactions, using a range of 2- and 3-substituted furans, is reported. Substituted oxabenzonorbornadiene
