  Even acyclic tertiary amines such as triethylamine, tri-n-propylamine and tri-n-butylamine, which have been believed to be inert to aromatic and heteroaromatic halides, underwent SNAr reactions with aromatic and heteroaromatic halides to give the dialkylamino derivatives; in the case of monocyclic amines like N-methylpyrrolidine and N-methylpiperidine, the dealkylation being regioselective.

  Carbon nitride (CN)-supported nanosized palladium particles, Pd–CN, have been found to be an active catalyst system for the amination of aryl and pyridyl chloride moieties in the presence of dialkyl amine under mild reaction conditions. The recyclability study of the reaction shows the stable performance of the catalyst without a significant loss of catalytic activity for a couple of cycles.

  已经发现，在温和的反应条件下，在二烷基胺存在下，氮化碳（CN）负载的纳米钯颗粒Pd-CN是一种用于芳基和吡啶氯部分胺化的活性催化剂体系。反应的可循环性研究表明，在几个循环中，催化剂的性能稳定，而催化活性没有明显损失。

  mainly via an SRNl mechanism involving single electron transfer (SET) from the nitroxide 2 to the substrate 3 leading to the radical anion (21) and hence the tetrafluoro-4-pyridyl radical (22) which reacted with 2 at nitrogen to afford the amine oxide 20. Major Meisenheimer rearrangement of 20 gave hydroxylamine 9, while minor rearrangement afforded the hydroxylamine Py-N(Et)OEt (23) which eliminated

  3-Nitropyridine was reacted with ammonia or alkylamines and KMnO4 under several different conditions. Substitutions in the pura posit ion to the nitro group were obtained with high regio selectivity: with ammonia, 2-amino-5-nitropyridine (66%), with butylamine, 2-butylamino-5-nitropyridine (92%), with diethylamine, 2-diethylamino-5-nitropyridine (49%). Under the same conditions, with methyl-3-nitroisonicotinoate and diethylamine/KMnO4, methyl 2-diethylamino-5-nitroisonicotinoate (48%), with 4-acetyl-3-nitropyridine (protected by ethylene glycol) 2-diethylamino-4-acetyl-5-nitropyridine (72%, protected) and with 4-cyano-3-nitropyridine, 2-amino-4-cyano-5-nitropyridine (41%) were obtained.
