Macrocycles of type 2 with up to 26 ring atoms ( n = 22) are available in very good yields by photo electron transfer (PET) initiated decarboxylation of the anions of N ‐phthaloyl‐ω‐aminocarboxylic acids 1 . The electron transfer is favored as a result of intramolecular K + ‐mediated chelation; however, it can also occur efficiently over larger donor‐acceptor distances.
