Here we demonstrate N-aryl aziridine synthesis via 1) olefin aziridination with N-aminopyridinium reagents to afford N-pyridinium aziridines followed by 2) Ni-catalyzed C–N cross-coupling of the N-pyridinium aziridines with aryl boronic acids. The N-pyridinium aziridine intermediates also ...

pyridinium saltsstrained moleculesThrough the formation of an electron donor-acceptor (EDA) complex, strain-release aminopyridylation of [1.1.1]propellane with N-aminopyridinium salts as bifunctional reagents enabled the direct installation of amino and pyridyl groups onto bicyclo[1.1.1]pentane (BCP) ...
A method for the construction of 2-fluoropyrazolo[1,5-a]pyridines through base-promoted [3+2] cycloaddition of N-aminopyridinium salts with gem-difluorostyrenes has been established. A range of N-heterocycles with 2-fluorinated pyrazo[1,5-a]pyridines were efficiently obtained in moderate to ...

In a four-step synthesis, a series of N-arylideneamino p-substituted pyridinium salt derivatives were prepared for use as cationic azomethine disperse dyes for polyester and polyacrylonitrile fibres. The effect of different substituents, in both of homo- and heterocyclic ring systems, on position of...
