SYNTHESIS AND CHARACTERIZATION OF 2,6- AND 2,7- DISUBSTITUTED BIPHENYLENS

Autor: Omar Abou-Teim

Publikováno v: Al-Azhar Bulletin of Science. 17:77-84

Many 2,6-disubstitued biphenylenes were prepared which are expected to have liquid crystal properties; also 2,7-disubstituted biphenylenes, which might also show mesogenic properties, were synthesized.

Benzocyclobutenes. Part 9. Synthesis of bromo-, chloro-, and oxo-derivatives of benzocyclobutene and naphtho[b]cyclobutene

Autor: Omar Abou-Teim, Michael C. Goodland, John F. W. McOmie

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :2659

Addition of benzyne to 1,1-dichloro- and 1,1,2-trichloro-ethene gave the corresponding di-(61%) and tri-(18%) chloro derivatives of benzo-cyclobutene. Similarly 2,3-didehydronaphthalene and 1,1-dichloroethene gave 1,1-dichloronaphtho[b]cyclobutene. S

Benzocyclobutenes. Part 5. Synthesis of 4-hydroxy-, 4,5-dihydroxy-, and 3,6-dihydroxy-benzocyclobutene-1,2-dione (benzologues of semisquaric and squaric acid)

Autor: David H. Perry, Robert B. Jansen, John F. W. McOmie, Omar Abou-Teim

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :1841

4-Methoxy- and 4,5-dimethoxy-benzocyclobutene-1,2-dione have been made by flash vacuum pyrolysis of the anthracene adducts of the corresponding phthalazine-1,4-diones which were prepared from the appropriate methoxyphthalic anhydrides. 3,6-Dimethoxyb
