Abstract

A process for the catalytic reduction of nitrous oxide using NHC-ligated copper(I) tert-butoxide precatalysts and B₂pin₂ as the reductant is reported. These reactions proceed under mild conditions via copper(I)-boryl intermediates which react with N₂O by facile O-atom insertion into the Cu−B bond and liberate N₂. Turnover numbers >800 can be achieved at 80 °C under 1 bar N₂O.
