Abstract
C–O bond breaking is an important process in the activation of CO2 that can be catalyzed by the presence of a metal. In this talk, we investigate the factors that lead to bond insertion in [M(CO2)y] − gas phase clusters, specifically addressing differences amongst the metals M = Ni, Fe, and Ti. Gas phase anionic clusters were generated using laser ablation of a metal target in the presence of a CO2 expansion, and the infrared photodissociation spectra were measured from 950–2400 cm−1 . Metal carbonyl vibrational signatures were used to infer bond insertion, and computational chemistry simulations were used to assess the feasibility of bond breaking in these systems.
