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.
