Aliphatic secondary nitro compounds are converted to ketones at room temperature, usually in 90–100% yields, by a one-pot reaction with 220–250 mol % of trimethylphosphine (PMe3) and 50–100 mol % of tBuC6H4SSC6H4tBu or PhthN-SePh, or 20 mol % of both additives. Thus, very mild catalytic variants of the reductive Nef-like reactions are disclosed.
脂肪族仲硝基化合物在室温下通过一锅反应与220–250 mol%的三甲基膦(PMe 3)和50–100 mol%的t BuC 6 H 4转化为酮,通常产率为90-100%。SSC 6 H 4 t Bu或PhthN-SePh,或两种添加剂的20摩尔%。因此,公开了还原性Nef样反应的非常温和的催化变体。
