Application

Ammonium nitrate can be used as a catalyst:
  • For the direct conversion of aryls, heteroaryls, and aliphatic esters to amides.
  • To synthesize 2-aminothiazoles via aerobic oxidative cyclization of ketones with thioureas.
It can also be used to quench Mizoroki-Heckreaction.

We present a gnotobiotic system for microbiota reconstitution on Arabidopsis thaliana under contrasting iron availability. This system induces iron starvation in plants by providing an unavailable form, mimicking conditions in alkaline soils. Inoculation of taxonomically diverse bacteria reconstitutes plants with
