Graphic abstract: Probing the aromaticity in 2,3-pyrido-annulated N-heterocyclic carbene and its heavier analogues

Abstract: The aromaticity in 2,3-pyrido-annulated 1,3,2λ²-diazatetroles C₅H₃N(NR)₂E^II (E^II = C, Si, Ge, Sn, Pb) was studied using a set of experimental and calculated criteria: UV-VIS, Raman, ISE, NICS, GIMIC and EDDB. The data obtained indicate either a slight decrease in aromaticity (NICS, GIMIC, ISE methods) or equal aromaticity (UV-VIS, ISE methods) compared to benzo-annulated analogues C₆H₄(NR)₂E. The π-aromaticity increases down the group from Si to Pb.

Keywords: tetrylenes, heavier carbene analogues, aromaticity, Raman spectroscopy, electron density of delocalized bonds, gauge- including magnetically induced currents.
