Synthesis of Quinolino[4,3‐j]phenanthridines and their Photophysical Characterization

European Journal of Organic Chemistry, Volume 28, Issue 13, April 1, 2025.
Nine novel quinolino[4,3‐j]phenanthridines were successfully synthesized. UV/Vis and fluorescence spectroscopy revealed remarkable optoelectronic properties. Large Stokes shifts were especially observed for the protonated substrates. The experimental results were compared and complemented with quantum chemical calculations, providing further insights ...

Ortho Arylation of N‐Aryl Amides and the Construction of Diagonal Tetraarylbenzenediamines and N‐Doped Fulminenes via BBr3‐Derived Dibromoboracycles

Chemistry – A European Journal, Volume 31, Issue 8, February 6, 2025.
We report the discovery of a boron‐driven ortho‐arylation reaction of N‐aryl amides and ureas. This novel method enables directed borylation of a wide range of substrates, leading to the synthesis of unique compounds such as N‐doped fulminene and diagonal tetraarylbenzenediamines.
