Mechanochemical synthesis of freebase and metal corroles

Herein, we report on the mechanochemical reaction of pyrrole and substituted benzaldehyde precursors to produce freebase corroles demonstrate one-pot synthesis 5,10,15-Tris(4-t-butylphenyl)corrole (H3t-buPhC), in which both, condensation oxidation reactions steps, took place ball mill. Moreover, could achieve copper with decent overall yields 10–12%. With approach shift EcoScale obtained from common procedures significant more positive values E-factor for insertion was lowered by factor 3.0.
