A process for the catalytic reduction of nitrous oxide using NHC-ligated copper(I) tert-butoxide precatalysts and Bpin as the reductant is reported. These reactions proceed under mild conditions via copper(I)-boryl intermediates which react with NO by facile O-atom insertion into the Cu-B bond and liberate N. Turnover numbers >800 can be achieved at 80 °C under 1 bar NO.
报道了一种使用N-杂环卡宾配位的叔丁醇铜（I）预催化剂和频哪醇硼烷（Bpin）作为还原剂催化还原一氧化二氮的方法。这些反应在温和条件下通过铜（I）-硼基中间体进行，该中间体通过将O原子容易地插入Cu-B键中与NO反应并释放出N。在80°C、1巴NO压力下，周转数可超过800。
