Reactions of Phenolic Mannich Bases with Phenols

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1958
1)フェノールマンニッヒ塩基とフェノール類との反応は,フェノール性OH基の酸性度が大きいほど分解反応大でまたフェノール類添加により促進されるが,アニソールのようにOH基を有しないと促進しない。2)ニトロフェノール,アニリン等の添加により分解反応が促進される。また,これがオルトマンニッヒ塩基と,パラ,マンニッヒ塩基とにより大きく差を生じ,オルトマンニッヒ塩基において効果大で,パラマンニッヒ塩基であまり効果を認めなかった。3)オルトマンニッヒ塩基で,2,4-二置換フェノールを用いたものと相手フェノールを2,4-ジメチルフェノールとの,反応で, 発生ジメチルアミンの追跡により, 初期反応を2 次反応速度として取扱うことができる。マンニッヒ塩基の置換基RがCH3では活性化熱13.6kcal/mol ...
