    • In the present context, the terms evolution and evolve are used in the meaning of change into, as in prebiotic chemical evolution. It has been pointed out in ref 1a (p 4767) and by a referee that one may consider that evolution supposes heritable information/ features as in biological evolution

    • The presence of the central hydrazone unit makes the whole molecule dissymmetric. Therefore the two hemi-aminals do not have the same reactivity. The one on the pyridine aldehyde side is expected to be more stable than that on the pyridine hydrazine side

    • After addition of lead triflate, imine hydrolysis was observed. This can be explained by the fact that additional imines can coordinate the metallo-macrocycle in its axial position (see text) and therefore activate the imine towards a nucleophilic attack from residual water. Imidazole can prohibit that by occupying the axial position of the metallo-macrocycle as it has been previously proven see text, It also makes the medium more basic which helps the formation of imines
