PIIIPV═O Redox‐Catalyzed Direct Amide‐to‐Ketimine Transformation via Friedel–Crafts‐type C─C Bond Formation

open access: yesChemCatChem, 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 ...

Influence of the solvent and of the reaction concentration for palladium-catalysed direct arylation of heteroaromatics with 4-bromoacetophenone

open access: yes, 2014
International audienceThe solvent is certainly one of the main sources of wastes during palladium-catalysed direct arylation reactions. We found that such direct arylations of heteroaromatics can be performed using very high concentrations of reactants ...
