Tempo在酸中的歧化导致形成N-氧铵盐，该盐可在热条件下进一步分解，产生相应的羟胺、N(2O)O、CO(2)和一系列二聚产物。总体而言，TEMPO在酸催化下的热衰减导致羟胺的产率约为80%。
Disproportionation of TEMPO in acids leads to the formation of an N-oxoammonium salt, which can further decompose under thermal conditions, yielding the corresponding hydroxylamine, N(2)O, CO(2) and a series of dimerisation products. Overall, acid-catalysed thermal decay of TEMPO leads to ca. 80% yield of hydroxylamine.
