N-alkylation of amines by using secondary amides as the alkyl source was developed. A versatile type of carboxamide functioned as an N-alkylation reagent in the presence of an indium(III) catalyst and a hydrosilane to provide alkylated tertiary aminesefficiently. This amide-based catalytic N-alkylation strategy is considered to be a highly useful protocol to access unsymmetrical tertiary amines.
We develop an electrochemical nickel-catalyzed aminomethylation of arylbromides under mild conditions. The convergent paired electrolysis makes full use of anode and cathode processes, free of a terminal oxidant, a sacrificial anode, a metal reductant, and a prefunctionalized radical precursor. In addition, this method exhibits wide functional group tolerance (63 examples), including some sensitive
