unified approach to azepines by dearomative photochemical rearrangement of aromatic N-ylides. Deprotonation of quaternary aromatic salts with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) or N,N,N′,N’-tetramethylquanidine (TMG) under visible light irradiation provides mono- and polycyclic azepines in yields up to 98%. This ring-expansion presents a new mode of access to functionalized azepines from N-heteroarenes

Regioselective reaction of 2-bromomethyl-1,3-thiaselenole with pyridine and itsderivatives is followed by rearrangement with ring expansion and the formation of a bond between a nitrogen atom and a carbon in the position 2. A set of derivatives of 2,3-dihydro-1,4-thiaselenine was obtained, substituted in the position 2 by a pyridinium residue functionalized by pharmacophoric groups.
