Highly efficient reduction of carbon dioxide with a borane catalyzed by bis(phosphinite) pincer ligated palladium thiolate complexes

Abstract

Highly efficient catalytic reduction of CO₂ with catecholborane has been developed by using bis(phosphinite) pincer ligated palladium thiolate complexes. Turnover frequencies up to 1780 h⁻¹ have been achieved at room temperature under an atmospheric pressure of CO₂. These thiolate complexes represent the most efficient homogeneous catalysts known to date for the reduction of CO₂ to methanol under mild conditions.
