A Heterogenized Molecular Catalyst for the Gas-Phase Cyclotrimerization of Acetylene to Benzene.

ABSTRACT: Facilitating the cyclotrimerization of acetylene to benzene in the gas-phase on the surface of solid catalysts has captivated researchers, both theoretically and experimentally, for several decades. Coupled with acetylene production from renewable feedstocks, this reaction offers a promising pathway for the direct, low-temperature synthesis of renewable benzene. Recognizing the physical limitations of typical solid catalysts, which adsorb benzene too strongly, this study investigates various high-valent early transition metal chlorides─potent molecular cyclotrimerization catalysts─as solid catalysts in this gas-phase conversion. Alongside catalytic assessment under industrially relevant conditions, various analytical techniques such as ⁹³Nb solid-state NMR spectroscopy, X
