    • The iodopyridinedicarboxylate 4 is an intermediate in the synthesis of the concave pyridines 3. The conditions for the Sonogashira coupling were therefore first checked with this "cheaper" compound, which is why the resulting esters 5 were investigated for comparison.

    • Three sets of signals can be distinguished, but only the signals of the most intensive set (Z,Z) are given. Between 20 and 70 ppm the assignment of the signals may be incorrect, due to intense signal density.
