Chinolin-n-oxid

WebQuinoline N-oxide can be easily nitrated with benzoyl nitrate to give 3-nitroquinoline N-oxide (172) 〈57CPB56〉. The proposed mechanism is outlined in Scheme 45 and probably involves the initial reaction of benzoyl nitrate with the oxygen of the N -oxide. WebJun 18, 2024 · An efficient Cp*Co III-catalyzed C8-dienylation of quinoline-N-oxides was achieved by employing allenes bearing leaving groups at the α-position as the dienylating agents.The reaction proceeds by Co III-catalyzed C−H activation of quinoline-N-oxides and regioselective migratory insertion of the allene followed by a β-oxy elimination, leading to …
