Electrochemically generated hypervalent iodine(III) species are powerful reagents for oxidative C−N coupling reactions, providing access to valuable N‐heterocycles. A new electrocatalytic hypervalent iodine(III)‐mediated in‐cell synthesis of 1H‐N‐aryl‐3,4‐dihydroquinolin‐2‐ones by dehydrogenative C−N bond formation is presented. Catalytic amounts of the redox mediator, a low supporting electrolyte...
Acyliminium ions and related species are potent electrophiles that can be quite valuable in the synthesis of nitrogen‐containing molecules. This manuscript describes a protocol to form these intermediates through hydride abstractions of easily accessible allylic carbamates, amides, and sulfonamides that avoids the reversibility that is possible in classical condensation‐based routes. These intermediates...
