The parent nitrenum ion generated from N-aminopyridinium, S-aminosulphonium, or N-aminopyridinium salts interacts with both the unshared electron pair of the heteroatom of pyridine, sulphide, or bipyridyl and the gegen anion by hydrogen bonding; the singlet nitrenium ion is stabilised by this interaction, and the stabilised singlet state undergoes fast singlet -> triplet conversion in the presence of molecular oxygen or chlorine.
