A series of hexaarylbenzenes having two peripheral thienyliron substituents has been prepared, and it is revealed that the two metal centres communicate with each other through toroidal delocalization among the peripheral aromatic groups.
A simple method for the preparation of diaryl acetylenes in yields up to 61% from aryl bromides and 1-bromo-2-chloroethane using the palladium catalyst (dppb)Pd(OAc)2 under PTC conditions (solid KOH/18-crown-6) has been developed.
