Abstract Pharmacological properties of a bioactive molecule can be improved significantly by placing fluoroalkyl group on its scaffold. However, direct stitching groups to aromatic compounds via C−H bond activation or insertion reaction is difficult task, thus challenging and high demand. Herein, an alternative the Friedel‐Crafts alkylation, we describe uncharted strategy for selective efficient trifluoroethylation indole that relies iron(III)‐catalyzed proceeds Fe(III)‐carbene into C(sp 2 )−H using trifluoroacetaldehyde N ‐triftosylhydrazone as carbene precursor FeTPPCl catalyst.

Abstract We present a successful development of photo‐induced mono‐bromination method for anilines, which eliminates the requirement photocatalysts and excess bromine sources. Experimental investigations, complemented by computational analyses, establish that this operates via formation an electron donor‐acceptor (EDA) complex. This innovative approach enables synthesis highly regioselective mono‐brominated products across diverse range substrates, all achieved under mild reaction conditions.
