A rare metal-free nucleophilic nitrosoarene catalysis accompanied by highly hydrogen-bond-donor (HBD) solvent, 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), organocatalytically converts arylmethyl halides to aromatic carbonyls. This protocol offers an effective means to access a diverse array of aromatic carbonyls with good chemoselectivity under mild reaction conditions. The activation of arylmethyl halides
一种不含稀有金属的亲核亚硝基芳烃催化,伴随着高度氢键供体 (HBD) 溶剂,1,1,1,3,3,3-六氟-2-丙醇 (HFIP),有机催化将芳甲基卤化物转化为芳香羰基化合物。该协议提供了一种有效的方法,可以在温和的反应条件下获得具有良好化学选择性的多种芳香羰基化合物。HFIP 活化芳甲基卤化物以产生稳定的碳正离子以及在大气 O 2存在下原位生成的羟胺自动氧化为亚硝基芳烃是成功的关键。
