A convenient synthesis of multisubstituted azatriphenylenes is reported. [Ir(cod)Cl]2/diphosphine is an efficient catalyst for the [2 + 2 + 2] cycloaddition of biaryl-linked diynes with nitriles to give multisubstituted azatriphenylenes in high yields. Aromatic, heteroaromatic, aliphatic, and functionalized nitriles could be used for the reaction.

Methoxycarbonylation of aryl- and alkenylboron compounds was performed using the palladium(II) acetate/triphenylphosphine [Pd(OAc)2/PPh3] catalyst with p-benzoquinone as a stoichiometric oxidant in methanol at ambient temperature to obtain the corresponding methyl esters in good yields. A wide variety of functional groups including various carbonyl functionalities, nitrile, nitro, sulfone, and unprotected
thermal reactions of 4,4‘-disubstituted2,2‘-bis(phenylethynyl)biphenyls with 2,3,4,5-tetraphenylcyclopenta-2,4-dienone were carried out under neat conditions and in diphenyl ether at temperatures between 260 and 270 °C to give rise to 9,10,11,12,13,14-hexaphenylcycloocta[l]phenanthrenes as the adducts in 12−23% yields. We traced these results to the intramolecular [2 + 2] thermal cyclization of 2,2‘-b
