摘要:
An efficient and simple procedure for the direct conversion of aldehydes into the corresponding nitriles with (NH2OHHCl)-H-./dry Al2O3/MeSO2Cl or amides with (NH2OHHCl)-H-./wet Al2O3/MeSO2Cl are studied. (C) 2002 Elsevier Science Ltd. All rights reserved.

Novelrearrangement was found by reacting anilines with HCHO/H2O2 resulting in the synthesis of various benzaldoximes. The mechanism of the rearrangement is proposed and suggested that the rearrangement might proceed via unstable N-phenyloxazirane intermediate followed by the transfer of aryl moiety from nitrogen to carbon atom leading to the formation of benzaldoxime.
通过使苯胺与HCHO / H 2 O 2反应,发现了新颖的重排反应,从而合成了各种苯甲醛肟。提出了重排的机理,并提出重排可能通过不稳定的N-苯基恶嗪烷中间体进行,然后芳基部分从氮转移到碳原子,从而导致苯甲醛肟的形成。

The highly stereoselective conversion of aldehydes and ketones to their corresponding oximes with hydroxylamin hydrochloride are catalyzed by CuSO4 and K2CO3. This method occurs under mild reaction conditions with high yields.

reactions of a series of benzaldehyde oximes (1a−o) were studied by steady-state (product studies) and laser flashphotolysis methods. Nanosecond laser flashphotolysisstudies have shown that the reaction of the oxime with triplet chloranil (3CA) proceeds via an electron-transfer mechanism provided the free energy for electron transfer (ΔGET) is favorable; typically, the oxidation potential of the
