2,3-Dinitrobiphenyl is an organic compound characterized by the presence of two nitro groups (-NO2) attached to different carbon atoms of a biphenyl molecule. The biphenyl structure consists of two benzene rings connected by a single bond. This chemical is known for its potential applications in the synthesis of dyes and as an intermediate in the production of certain pharmaceuticals. It is also recognized for its environmental persistence and potential toxicity, which has led to concerns regarding its release into the environment. Due to its chemical structure, 2,3-dinitrobiphenyl can be a component in the analysis of environmental samples, particularly in studies related to the detection and remediation of pollutants.

7391-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7391-72-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7391-72:
(6*7)+(5*3)+(4*9)+(3*1)+(2*7)+(1*2)=112
112 % 10 = 2
So 7391-72-2 is a valid CAS Registry Number.

Palladium(II)-catalyzed coupling of electron-deficient arenes via C-H activation

Zhou, Lihong,Lu, Wenjun

scheme or table, p. 2124 - 2127 (2012/06/01)

Homocoupling and cross-coupling of electron-deficient arenes, including nitrobenzene, (trifluoromethyl)benzene, ethyl benzoate, etc., have been developed to afford biaryls using a catalytic system of Pd(OAc) 2/trifluoroacetic acid (TFA)/O2 or K2S 2O8. The crucial step is to tune the concentrations of arenes and the loading of TFA carefully to enhance the reaction rates and the selectivity of these couplings involving dual C-H activation.
