Carbon–carbon cleavage of aryl diamines and quinone formation using sodium periodate: a novel application
摘要:
A first novel synthetic utility of sodium periodate for aryl diamine carbon-carbon cleavage is described. Aryl 1,2-diamine compounds were successfully converted into corresponding nitriles, while the developed method is also useful for the preparation of quinones from corresponding aryl 1,4-diamine compounds. The advantages of this protocol are shorter reaction time and mild reaction conditions to obtain moderate to good yields. (C) 2010 Elsevier Ltd. All rights reserved.

Amination of naphtho[1,8-de]triazine with aqueous hydroxylamine-O-sulphonic acid gives 1-aminonaphtho-[1,8-de]triazine and 1-amino-8-azidonaphthalene. Amination with ethereal chloramine gives 1- and 2-aminonaphthotriazines and the latter was shown to rearrange to the amino-azide under the conditions of the hydroxylamine-O-sulphonic acid amination. Both 1 - and 2-aminotriazines are rearranged smoothly
用羟胺-O-磺酸水溶液胺化萘[1,8- de ]三嗪,得到1-氨基萘-[1,8- de ]三嗪和1-氨基-8-叠氮基萘。用醚化氯胺胺化得到1-和2-氨基萘三嗪,并且显示后者在羟胺-O-磺酸胺化的条件下重排成氨基叠氮化物。1-和3-氨基三嗪均被酸平滑地重排至氨基叠氮化物。将这些三嗪的稳定性与相关三唑的稳定性进行了比较,并提出了其重排的机理。
