Pd(OAc)2/1,10-phenanthroline-catalysed addition of potassium phenyltrifluoroborate to aliphatic dinitriles in 2-MeTHF has been developed, achieving diphenyl diones in moderate to excellent yields. The scope of the developed approach was successfully explored toward the addition of potassium phenyltrifluoroborate to aromatic dinitriles. Additionally, a plausible pathway for the formation of the diones has been proposed.

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.
