The albatrossenes: Large, cleft-containing, polyphenyl polycyclic aromatic hydrocarbons

The syntheses and X-ray structures of very large polycyclic aromatic compounds containing clefts defined by polyphenylaryl groups are described. The C2-symmetric 'albatrossenes' 1,3-bis(heptaphenyl-2-naphthyl)benzene (7a) and 1,3-bis(heptaphenyl-1-naphthyl)benzene (12a), as well as brominated derivatives, were synthesized by the addition of tetraphenylbenzyne to the appropriate polyphenyl biscyclopentadienones. The 2-naphthyl isomers have wide, shallow clefts, and the 1-naphthyl isomers have deep, narrow clefts which were observed to change size dramatically in different crystal environments. In a similar way, 1,3,5-tris(pentaphenylphenyl)benzene (19), a D3-symmetric molecular propeller with a diameter of 21 ?, and 1,3,5-tris(heptaphenyl-2-naphthyl)benzene (22) were prepared by the addition of diphenylacetylene and tetraphenylbenzyne, respectively, to a triscyclopentadienone.

Process for synthesizing bis (phenylglyoxyloyl)benzenes usable for manufacturing polyphenylquinoxaline resins

Bis (phenylglyoxyloyl) benzenes are manufactured by a method comprising the reaction of terephthalic or isophthalic aldehyde first with a low proportion of an alkali metal cyanide in a solvent, and then with benzaldehyde; the resultant product is oxidized to the desired bis (phenylglyoxyloyl) benzene.
