A breath of fresh air: The title reaction has been developed for the coupling of amines with nitroalkanes and different unmodified ketones using air as the sole oxidant under mild reaction conditions. The safe, convenient, and environmentally benign process, as well as the low catalyst loading, short reaction time, and good yields make this protocol very practical (see scheme).
呼吸新鲜空气:在温和的反应条件下,使用空气作为唯一的氧化剂,已开发出标题反应,用于将胺与硝基烷烃和不同的未改性酮偶联。安全,方便且对环境无害的过程,以及催化剂用量低,反应时间短和产率高的特点,使该方案非常实用(请参阅方案)。
