ChemCatChem, Volume 18, Issue 4, 25 February 2026.A series of ketimines were synthesized via electrophilic aromatic substitution on indole and pyrrole derivatives. This synthetic method is based on activating amides using PIII/PV═O redox catalysis, yielding an imidoyl chloride intermediate. Subsequent conversion with indole and pyrrole derivatives afforded 20 novel ketimines in yields up to 94 ...
