Description
4-Cyanobenzophenone is a benzophenone derivative characterized by its slightly yellow crystalline powder appearance. It can be synthesized by treating 4-cyanobenzoyl chloride with benzene, and its reduction under electrochemical conditions results in the formation of 4-t-butyl-benzophenone and 1-(4-cyanophenyl)-2,2-dimethyl-1-phenylpropan-1-ol. 4-CYANOBENZOPHENONE is known for its efficiency as a triplet sensitizer in the photoisomerization of norbornadiene (N) to quadricyclane (Q) and vice versa.

Check Digit Verification of cas no
The CAS Registry Mumber 1503-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1503-49:
(6*1)+(5*5)+(4*0)+(3*3)+(2*4)+(1*9)=57
57 % 10 = 7
So 1503-49-7 is a valid CAS Registry Number.

Herein we report ketones as feedstock materials in radical cross-coupling reactions under Ni/photoredox dual catalysis. In this approach, simple condensation first converts ketones into prearomatic intermediates that then act as activated radical sources for cross-coupling with aryl halides. Our strategy enables the direct benzylation/benzoylation of (hetero)arenes under mild reaction conditions with high functional group tolerance.
