Abstract
The thermal energy reactions of Ta+, Nb+, and NbL+ (L = O, N) with arenes in the gas phase result In cleavage of the aromatic rings with formation of metallacyclopentadiene ion complexes via a retro-alkyne cyclotrimerlzation mechanism. The ring cleavage reactions are proposed to involve bent arene Intermediates, analogous to recently observed Ta-and Nb-benzene complexes generated In solution by alkyne cyclotrimerlzation. The d° system NbO2+ reacts with pyridine exclusively via C-H bond activation Involving σ-metathesis transition state.
