We use kinetic data, photophysical properties, and mechanistic analyses to compare recently developed high-rate constant oxime and hydrazone formations. We show that when Schiff base formation between aldehydes and arylhydrazines is carried out with an appropriately positioned boron atom, then aromatic B–N heterocycles form irreversibly. These consist of an extended aromatic structure amenable to the
Hydroquinone–quinone oxidation by molecular oxygen: a simple tool for signal amplification through auto-generation of hydrogen peroxide

Signal amplification methods are of obvious importance for various diagnostic assays. We have developed a new small-molecule-based probe that, upon activation with sub-stoichiometric amounts of hydrogen peroxide, produces an auto-inductive amplification reaction. The signal is produced through the oxidation reaction of hydroquinone to the corresponding quinone derivative by molecular oxygen. This oxidation is accompanied by the formation of hydrogen peroxide, which can enter the amplification sequence and initiate a new diagnostic cycle. The generated quinone is composed of a donorâacceptor conjugated pair and fluoresces at a distinct wavelength, allowing the formation to be monitored by a convenient fluorescence assay.
