Nitration - Wikipedia
WebThe current reaction mechanism is primarily the oxidation reaction including oxidation of boronic acids and its ester derivatives, oxidation-induced cleavage of ethylenic bond, oxidation of α-ketoamide derivatives, and so on, which means simple sensing mechanism and probes may interfere with other active species such as H 2 O 2.
