Various binding modes of pyrido[2,1-a]isoindole with main-group and transition-metal elements have been established. The carbon atom at position 6 of pyrido[2,1-a]isoindole is highly nucleophilic, forming a σ complex with Pt(II) ion. The benzene ring of pyrido[2,1-a]isoindole forms an η6-π complex with Cr(0). The reaction of pyrido[2,1-a]isoindole with PPh2Cl in the presence of Proton Sponge leads to a PPh2-functionalized product, which can further react with a BH3 molecule, forming a P→B adduct. Pyrido[2,1-a]isoindole was also found to undergo a dehydrogenative C–C coupling reaction in the presence of Cu(I) ions, forming a dimer. These interesting reactivities and binding modes demonstrate the rich chemistry of pyrido[2,1-a]isoindole, as well as its potential application in main-group and transition-metal chemistry.
