概要
- 論文の詳細を見る
Varied aliphatic non-cyclic amines (II〜X) were prepared and oxidized in the hope of elucidating some fundamental aspects of the Robinson dehydrogenation reaction. In the case of tertiary amines the cyclization was brought about most smoothly, whereby five-membered ring was likely to be formed preferentially over a six-membered one. In secondary amines, yields were varied presumably due to side or secondary reactions, while primary amines were shown to be unsuitable for this reaction.
