C–H activation reaction has been developed
for the preparation of pyridinium salts from secondary allylamines
and internal alkynes. The pyridinium salts formed by this N-annulation reaction have interesting fluorescence properties.
This protocol has been applied to the surface modification of mesoporous
silica materials to generate functionalized silica that can be used
for the detection of nitrobenzene.
