Abstract A novel and efficient electrochemical oxidative transamidation of tertiaryamines with N-acyl imides is described. This protocol is environmentally friendly and ease to handle as tertiaryamines are used as surrogates for secondary amines. The C-N bond of tertiaryamines is cleaved, preparing amide compounds in a facile approach with 29 examples in 11–80% yields.

three-component reaction of amides, alkyl halides, and 18O-labeled water. This method demonstrated excellent selectivity and compatibility with various amides and alkyl halides, allowing the synthesis of diverse isotopicallylabelled esters. Ni-catalyzed reaction of alkyl bromides, carboxylates that generated from amides, and water in the presence of a base formed the desired esters.
