As part of a research program aimed at functional mimicry of heterocyclic scaffolds through boron isosterism, we recently explored the synthesis of a novel class of boron-containing heterocycles - boramidine -which turned out to exhibit violet-blue fluorescence (378 -425 nm, 2.91 eV -3.28 eV, dichloromethane). Boramidine features a 6,5-fused boron-containing heterocyclic core that is assembled rapidly in a single synthetic step from 2-aminopyridine and N-alkyl nitrilium aminoborane 4a.
