Caution, wet ligand! An alternative mechanism for acetylene [2+2+2] cyclotrimerization to benzene catalyzed by RhI half-metallocenes is proposed (see figure), based on an extensive computational exploration and electronic structure analyses. The mechanism explains the experimentally observed indenyl effect in terms of a more facile slippage of [RhI] on the indenyl versus cyclopentadienyl ligand.
