Abstract
AbstractCorrole and sapphyrin with the smallest meso‐substituents reported so far were prepared in a one‐pot synthesis that relies on a non‐aldehydic precursor for introducing CF3 groups. The substantial amounts of products obtained by this facile pathway allowed for the full characterization of 5,10,15‐tris(trifluoromethyl)corrole, the access to a variety of stable chelates thereof and investigations that disclose the unique structural and chemical properties induced by the CF3 substituents. The novel 5,10,15,20‐tetra(trifluoromethyl)sapphyrin undergoes only single protonation, which according to its crystal structure is stabilized by favorable non‐bonding F/H interaction between the meso‐CF3 and the inverted pyrrolic NH.
