Radical C?N Borylation of Aromatic Amines Enabled by a Pyrylium Reagent

Herein, we report a radical borylation of aromatic amines through a homolytic C(sp2)?N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent (ScPyry-OTf) thus priming the amino group for reacti

Boron Trifluoride as a Cyclodehydrating Agent: Synthesis of Nitrogen Heterocycles via Pyrylium Tetrafluoroborates

Pyrylium cations (1-12,Z = O+) have been prepared in high yields by the interaction of chalkones (in slight excess) and different ketones using BF3-etherate as cyclodehydrating agent or from 1,5-diketones in the presence of HBr and chalkone as hydrogen abstractor.The pyrylium cations have been converted into the corresponding nitrogen heterocycles (1-12;Z=N).
