1-Phenylbiphenylene, also known as 1-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 carbon-carbon bond. The phenyl group is attached to one of the biphenyl rings, making it a substituted biphenyl. 1-phenylbiphenylene is of interest in organic chemistry and materials science due to its unique structure and potential applications in the synthesis of various compounds. It is typically synthesized through various methods, such as the Friedel-Crafts reaction, and can be used as a building block for more complex molecules or as a precursor in the production of certain pharmaceuticals and specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 1436-33-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1436-33:
(6*1)+(5*4)+(4*3)+(3*6)+(2*3)+(1*3)=65
65 % 10 = 5
So 1436-33-5 is a valid CAS Registry Number.

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 (2004)

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
