1,7-Diphenylnaphthalene is an organic compound with the chemical formula C26H20. It is a derivative of naphthalene, featuring two phenyl groups attached to the first and seventh carbon atoms of the naphthalene ring. This molecule is characterized by its planar structure and strong π-π interactions between the phenyl rings and the naphthalene core. 1,7-Diphenylnaphthalene is known for its unique photophysical properties, such as strong fluorescence and large Stokes shifts, making it a potential candidate for applications in organic light-emitting diodes (OLEDs), sensors, and other optoelectronic devices. The compound can be synthesized through various methods, including the Friedel-Crafts alkylation of naphthalene with benzene in the presence of a Lewis acid catalyst. Due to its stability and interesting electronic properties, 1,7-diphenylnaphthalene has been widely studied in the field of organic chemistry and materials science.

970-06-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 970-06-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 970-06:
(5*9)+(4*7)+(3*0)+(2*0)+(1*6)=79
79 % 10 = 9
So 970-06-9 is a valid CAS Registry Number.

Cross-coupling of aryl/alkenyl silyl ethers with grignard reagents through nickel-catalyzed CO bond activation

Zhao, Fei,Yu, Da-Gang,Zhu, Ru-Yi,Xi, Zhenfeng,Shi, Zhang-Jie

supporting information; experimental part, p. 1001 - 1003 (2011/12/05)

CO activation and its application have drawn much attention since oxygen-based electrophiles are easily available, less toxic, and more environmentally benign. This letter presents systematically results on the Ni-catalyzed KumadaTamaoCorriu coupling based on siloxy arenes/alkenes, which provides a new strategy of silyl protection/CC bond formation sequence in organic synthesis.

Polycondensation of naphthalene and its alkyl derivatives

Golounin,Marakushina,Khramenko

experimental part, p. 2137 - 2140 (2009/06/05)

Polycondensation of naphthalene and its alkyl derivatives (stripping oil, 2,5-dimethylnaphthalene) in the presence of aluminum halides was performed. Under the action of an ultrasonic field on a benzene solution of naphthalene in the presence of the catalyst, intermolecular condensation and benzene addition are observed.
