Bottleable (Amino)(Carboxy) Radicals Derived from Cyclic (Alkyl)(Amino) Carbenes

Monomeric (amino)­(carboxy) radicals were synthesized in two steps: the addition of a stable cyclic (alkyl)­(amino) carbene to an acyl chloride, followed by a one-electron reduction. Their stability toward dimerization also allows for the synthesis of related bi- and triradicals.
