Abstract
Systematic studies on regioselective functionalization reactions employing oxygen-,
nitrogen-, and sulfur-containing nucleophiles with bismuth A3-corroles under the influence of a strong non-nucleophilic base are reported. In the
case of the thiols and dithiols a high-yielding reaction procedure was established
to obtain mono-, di-, and tri-functionalized corroles at room temperature within short
reaction times. The described method offers a possibility to attach bifunctional linker
molecules to the para-position of the meso-pentafluorophenyl groups at positions 5, 10, and 15 of the corrole macrocycle. The
described reaction strategy may serve as a versatile protocol for the covalent binding
of corroles to proteins or antibodies and may be utilized to attach corroles on, for
example, gold or titanium surfaces to study surface-supported reactions.
