63796-41-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63796-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,7,9 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 63796-41:
(7*6)+(6*3)+(5*7)+(4*9)+(3*6)+(2*4)+(1*1)=158
158 % 10 = 8
So 63796-41-8 is a valid CAS Registry Number.

Site-Selective Electrochemical Benzylic C?H Amination

C?H/N-H cross-coupling is an ideal strategy to synthesize various amines but remains challenging owing to the requirement for sacrificial chemical oxidants and the difficulty in controlling the regio- and chemo-selectivity. Herein we report a site-selective electrochemical amination reaction that can convert benzylic C?H bonds into C-N linkages via H2 evolution without need for external oxidants or metal catalysts. The synthetic strategy involves anodic cleavage of benzylic C?H to form a carbocation intermediate, which is then trapped with an amine nucleophile leading to C?N bond formation. Key to the success is to include HFIP as a co-solvent to modulate the oxidation potentials of the alkylbenzene substrate and the aminated product to avoid overoxidation of the latter.
