2-Phenylbiphenylene, also known as 2-phenyl-1,1'-biphenyl, is an organic compound with the molecular formula C18H14. It is a derivative of biphenyl, consisting of two phenyl rings connected by a single bond, with one phenyl ring substituted at the 2-position. 2-phenylbiphenylene is characterized by its planar structure and exhibits unique electronic properties due to the conjugation between the two phenyl rings. 2-Phenylbiphenylene is primarily used as a precursor in the synthesis of various organic compounds and as a ligand in coordination chemistry. It is also of interest in materials science for its potential applications in the development of novel electronic and optical materials.

1026-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1026-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1026-55:
(6*1)+(5*0)+(4*2)+(3*6)+(2*5)+(1*5)=47
47 % 10 = 7
So 1026-55-7 is a valid CAS Registry Number.

A Cobalt-catalysed Biphenylene Synthesis

Berris, Bruce C.,Lai, Yee-Hing,Vollhardt, Peter C.

, p. 953 - 954 (1982)

o-Diethynylbenzene is catalytically co-cyclised with alkynes in the presence of dicarbonyl(cyclopentadienyl)cobalt to provide a versatile synthesis of the biphenylene nucleus.

A p-benzyne to m-benzyne conversion through a 1,2-shift of a phenyl group. Completion of the benzyne cascade

Polishchuk, Alexei L.,Bartlett, Kevin L.,Friedman, Lee A.,Jones Jr., Maitland

, p. 798 - 806 (2007/10/03)

Pyrolysis of 1,6-diphenylhexa-1,5-diyne-cis-3-ene at 800-1000 °C leads to a mixture of 1- and 2-phenylbiphenylene, along with triphenylene. Formation of the two biphenylenes is taken as strong evidence of the rearrangement of a p-benzyne into a m-benzyne through a shift of one of the phenyl groups. Copyright
