In an article, published in an article, once mentioned the application of 1806-29-7, Name is 2,2-Biphenol,molecular formula is C12H10O2, is a conventional compound. this article was the specific content is as follows.Quality Control of: 2,2-Biphenol
The interaction of 5,5?-dibromophenyl-17-crown-5 with triisopropylphosphite (NiBr2 catalysis) was employed to prepare 5,5?-bis(di-iso-propoxyphosphoryl)biphenyl-17-crown-5, its molecular structure (X-ray crystallography) being compared with the data for the unsubstituted biphenyl-17-crown-5 and an acyclic analog 2,2?-dimethoxy-5, 5?-bis(di-iso-propoxyphosphoryl)biphenyl. For both crown-ethers the macrocycle shape in the crystal state is defined by mutual rotation of the benzene rings, whilst bulky isopropoxyphosphoryl groups in the 5(5?) positions gave little influence on the dihedral angle made by the aromatic cycles. The P=O bonds of these groups are pointing into opposite directions and are virtually parallel to the benzene ring planes. The 2,2?-oxygen atoms of the biphenyl fragment have the gauche orientation in all compounds studied.
