Azines react with aromatic ketones, in the presence of lithium di-isopropylamide (LDA), giving rise to mono- and di-hydroxyazines; the reaction of these compounds with AlCl3 affords α,β-unsaturated azines and 5,5-disubstituted-5,6-dihydro-4H-1,2-diazepines, respectively.
在二异丙基氨基锂(LDA)存在下,叠氮与芳族酮反应,生成单羟基和二羟基嗪。这些化合物与AlCl 3的反应分别得到α,β-不饱和嗪和5,5-二取代的5,6-二氢-4 H -1,2-二氮杂。
