eliminated to form products of type Bt-CHR-NR′R″. The latter are versatile intermediates for the preparation of primary, secondary, and tertiary amines and in the alkylation of hydroxylamines, hydrazines, amides, thioamides, and sulfonamides. Polyfunctional amines and other polyfunctional compounds can also be prepared, and they enable significant extending of Mannich reaction.
苯并三唑和醛可逆地反应生成加成产物:在胺和其他NH化合物存在下,可以消除水形成Bt-CHR-NR'R''型产物。后者是用于制备伯胺,仲胺和叔胺以及羟胺,肼,酰胺,硫酰胺和磺酰胺烷基化的通用中间体。也可以制备多官能胺和其他多官能化合物,它们使曼尼希反应显着扩展。
