This also led to the first alternate form of meta-terphenyl synthesis, which involved passing gaseous benzene and toluene through a hot glass tube. By the s, focus had shifted to experimenting with the reactivity of meta-terphenyl and its potential use as a ligand. The first verified modified version of meta-terphenyl was created in by Arthur Wardner and Alexander Lowy and led to the creation of nitro-substituted meta-terphenyls as well as amino-meta-terphenyls from the oxidation of the nitro-substituted compounds.

Terphenyl

Terphenyls are a group of closely related aromatic hydrocarbons. Also known as diphenylbenzenes or triphenyls , they consist of a central benzene ring substituted with two phenyl groups. There are three substitution patterns : ortho -terphenyl, meta -terphenyl , and para -terphenyl. Commercial grade terphenyl is generally a mixture of the three isomers. This mixture is used in the production of polychlorinated terphenyls , which were formerly used as heat storage and transfer agents. One example is atromentin , a pigment found in some mushrooms. These natural p -terphenyls are better described as diphenylquinones or diphenylhydroquinones. Some m-terphenyl compounds occur in plants. Contents move to sidebar hide. Article Talk.

It has additionally helped in methyl-bridging bonds between transition metal centers. These natural p -terphenyls are better described as diphenylquinones or diphenylhydroquinones. Ames also wrote an article detailing not only reactions of meta-terphenyls, but also covering all the different experimental methods to obtain meta-terphenyl known at the time. By reacting anionic diphenyl molecules with functional ketones in a solution of potassium hydroxide and DMF in an ultrasound bath, a bulky meta-terphenyl molecule can be obtained.

As the demand for meta-terphenyl and its derivatives grew through the latter half of the 20 th century, it became necessary to increase the yield of reactions producing meta-terphenyls as well as have the ability to uniquely create symmetric and unsymmetric meta-terphenyls to investigate their reactivity as well utilize their increased steric control. This method continues to remain very popular in terms of the creation of symmetrical meta-terphenyl compounds, but that has not stopped attempts to quicken synthesis, increase yield, and create more sterically bulky m-terphenyls.
