^aThe pairwise reactions (30 mM for each reactant) were carried out for 24 h at 60°C in aqueous solution (pH 7) in the presence or absence of organic constituents (“oil slick”).

^bEtio denotes etioporphyrins from the reaction of 1-Me + 2-Et.

^cCopro denotes coproporphyrins from the reaction of 1-Me + 2-PrOH.

^dUro denotes uroporphyrins from the reaction of 1-AcOH + 2-PrOH.

^ePorphyrin yields upon chemical oxidation (with I₂).

^fAqueous solution containing 0.1 M decanoic acid.

^gAqueous solution (0.4 mL) and dodecane (0.1 mL).

^hAqueous solution (0.4 mL) and mesitylene (0.1 mL).

ⁱAqueous solution (0.4 mL) and the five-component organic mixture (0.1 mL).
