Reduction of CO₂ by a masked two-coordinate cobalt(i) complex and characterization of a proposed oxodicobalt(ii) intermediate.

ABSTRACT: Fixation and chemical reduction of CO₂ are important for utilization of this abundant resource, and understanding the detailed mechanism of C-O cleavage is needed for rational development of CO₂ reduction methods. Here, we describe a detailed analysis of the mechanism of the reaction of a masked two-coordinate cobalt(i) complex, L ^tBuCo (where L ^tBu = 2,2,6,6-tetramethyl-3,5-bis[(2,6-diisopropylphenyl)imino]hept-4-yl), with CO₂, which yields two products of C-O cleavage, the cobalt(i) monocarbonyl complex L ^tBuCo(CO) and the dicobalt(ii) carbonate complex (L ^tBuCo)₂(μ-CO₃). Kinetic studies and computations show that the κN,η⁶-arene isomer of L
