Allylic amines are valuable synthetic targets en route to diverse biol. active amine products. Current allylic C-H amination strategies remain limited with respect to the viable N-substituents. Herein, authors disclose a new electrochem. process to prepare aliphatic allylic amines by coupling two abundant starting materials: secondary amines and unactivated alkenes. This oxidative transformation proceeds via electrochem. generation of an electrophilic adduct between thianthrene and the alkene substrates. Treatment of these adducts with aliphatic amine nucleophiles and base provides allylic amine products in high yield. This synthetic strategy is also amenable to functionalization of feedstock gaseous alkenes at 1 atm. In the case of 1-butene, high Z-selective crotylation is observed This strategy, however, is not limited to the synthesis of simple building blocks; complex biol. active mols. are suitable as both alkene and amine coupling partners. Preliminary mechanistic studies implicate vinylthianthrenium salts as key reactive intermediates. The experimental part of the paper was very detailed, including the reaction process of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride)
