Three homoleptic tris-cyclometalated iridium (III) complexes (Ir1–Ir3) based on a rigid aza-triptycene unit have been synthesized via a novel one-pot method. The coordination arrangement of Ir2 was revealed by single X-ray structural analysis and the mole

A new class of roof-shaped dibenzobarrelenemaleimide derivatives was prepared by the condensation of a bridged maleic anhydride with amines. A para-substituted bifunctional derivative was proven to be a 1:2 complex with acetone by an X-ray crystallographic study.
Orbital unsymmetrization affects facial selectivities of Diels-Alder dienophiles

We investigated the Diels-Alder reactions of maleic anhydrides embedded in a dibenzobicyclo-[2.2.2]octatriene motif as a nonsterically biased dienophile. Substituents on a benzene ring in these dienophiles are far from the reaction center, providing a sterically equivalent π-face. Instead substituents can unsymmetrize the dienophilic π face through π* (anhydride)-π* (aromatic) orbital interactions. Electron-withdrawing substituents affect the facial bias and relative rates of these cycloadditions. The preference of the cycloadditions is opposite in direction to those observed in nucleophilic additions of 2-substituted-9,10-dihydro-9,10-ethanoanthracen-11-ones (dibenzobicyclo-[2.2.2]octadienones) and in electrophilic additions of 2-substituted 9,10-dihydro-9,10-ethenoanthracenes (dibenzobicyclo[2.2.2]octatrienes), though all of them have related dibenzobicyclic systems.
