Synthesis of linear α,β-unsaturated aldehydes via a room-temperature oxidative dehydrogenation has been realized by the cocatalysis of an organic nitrite and palladium with molecular oxygen as the sole clean oxidant. Linear α,β-unsaturated aldehydes could be efficiently prepared under aerobic catalytic conditions directly from the corresponding saturated linear aldehydes. Besides linear products, the
通过有机亚硝酸盐和钯与分子氧作为唯一的清洁氧化剂的共催化,已经实现了通过室温氧化脱氢合成线性α,β-不饱和醛。线性α,β-不饱和醛可以在需氧催化条件下直接由相应的饱和线性醛有效地制备。除线性产品外,通过相同的标准方法也可以顺利实现芳香族类比。有机亚硝酸盐氧化还原助催化剂和醇溶剂在实现该方法中起着关键作用。
