Abstract

We report the hydroboration of CO₂ with catecholborane catalyzed by a series of bis(phosphinite) pincer ligated nickel thiolate complexes. Turnover frequencies (TOFs) up to 2400 h⁻¹ were achieved at room temperature under an atmospheric pressure of CO₂. This represents the highest TOF value known to date for the reduction of CO₂ to the methoxide level under mild conditions.
