  2. Biphenyl - Wikipedia

    en.wikipedia.org/wiki/Biphenyl

    Biphenyl (also known as diphenyl, phenylbenzene, 1,1′-biphenyl, lemonene [4] or BP) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl .

  3. Bisphenol - Wikipedia

    en.wikipedia.org/wiki/Bisphenol

    [1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name ; the letter following denotes the variant, which depends on the additional substituents.

  4. Bisphenol A - Wikipedia

    en.wikipedia.org/wiki/Bisphenol_A

    The synthesis of BPA still follows Dianin's general method, with the fundamentals changing little in 130 years. The condensation of acetone (hence the suffix 'A' in the name) [ 33 ] with two equivalents of phenol is catalyzed by a strong acid, such as concentrated hydrochloric acid , sulfuric acid , or a solid acid resin such as the sulfonic ...

  5. 2,2'-Biphenol - Wikipedia

    en.wikipedia.org/wiki/2,2'-Biphenol

    2,2′-Biphenol is an organic compound with the formula (C 6 H 4 OH) 2. It is one of three symmetrical isomers of biphenol. A white solid, it is a precursor to diphosphite ligands that are used to support industrial hydroformylation catalysis. [1] [2] BiPhePhos is representative diphosphite ligand derived from 2,2′-biphenol.

  6. Phenyl group - Wikipedia

    en.wikipedia.org/wiki/Phenyl_group

    In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...

  7. Dihydroxybiphenyl - Wikipedia

    en.wikipedia.org/wiki/Dihydroxybiphenyl

    Dihydroxybiphenyl (as known as biphenol) refers to a class of organic compounds consisting of a biphenyl structure with two hydroxyl groups attached. The most common isomers are 2,2'-dihydroxybiphenyl and 4,4'-dihydroxybiphenyl.

  8. Diphenylacetylene - Wikipedia

    en.wikipedia.org/wiki/Diphenylacetylene

    The molecule consists of two phenyl groups attached to a C 2 unit. A colorless solid, it is used as a building block in organic synthesis and as a ligand in organometallic chemistry . Preparation and structure

  9. 4,4'-Biphenol - Wikipedia

    en.wikipedia.org/wiki/4,4'-Biphenol

    The industrial synthesis of 4,4′-biphenol was developed by Allan Hay in the 1960s. [2] [3] As the direct oxidative coupling of phenol gives a mixture of isomers, [4] [5] 4,4′-biphenol is instead prepared from 2,6-di-tert-butylphenol, where para-coupling is the only possibility. [3]
