Metal free porphyrins act as bifunctional organocatalysts

What is it about?

Porphyrins are known to be natural catalysts par excellence. In all these cases they contain a central metal which is involved in/or required for catalytic activity. Here we show for the first time that nonplanar fee base porphyrins without a metal can act as organocatalysts.

Why is it important?

it describes the first examples of porphyrins not containing a metal to be a catalyst. This has implications for developing new porphyrin-based catalysts or artificial enzymes.
