New discoveries in chemical research and development in 2021. Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage. In a patent，Which mentioned a new discovery about Safety of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, Safety of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine
Direct catalytic N-alkylation of amines with secondary alcohols via hydrogen autotransfer (HA) strategy is very challenging and has been scarcely reported, even under precious metal catalysis. Herein, an efficient N-alkylation of amines, including benzylamines using secondary alcohols as alkylating agents, is reported. This reaction is catalyzed by a molecularly defined NNN-Ni(II) pincer complex, and the reaction operates under mild, benign conditions. Various substrates and functional groups were tolerated. Preliminary mechanistic studies suggest that the N-alkylation reaction proceeds via a hydrogen autotransfer mechanism.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, you can also check out more blogs about22013-33-8
