水酸基含有化合物を触媒とするロイカルト反應による芳香族アミンのアミノアルキル化に就いて (第5報)

Abstract

1). In the previous report, it was shown that compounds possesssing hydroxyl group, such as ethylene glycol and phenol, acted as a catalyst in the Leuckart reaction of aromatic amines. In order to show that the action was due to the hydroxyl group, mono- and di-ethers of ethylene glycol or ether of phenol were added and the yields compared. As a result, it was shown that the presence of a free hydroxyl group was necessary in promoting the reaction.2). The fact that the velocity of the Leuckart reaction differred according to the kind and the amount of compounds containing hydroxyl group was shown by measuring, at defininite intervals, the amount of carbon dioxide gas generated.
