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。
