Diazeniumdiolates offer a versatile platform for development of both nitric oxide (NO) and nitroxyl (HNO) donors and have been vital to the study of chemical biology of nitrogen oxides. Derivatization of ionic diazeniumdiolates has been shown to improve the purification process, to dramatically slow the rate of spontaneous decomposition and to provide new therapeutic benefits as a function of addition of bioactive moieties. Decomposition of certain derivatized diazeniumdiolates can also yield acyl nitroso compounds as HNO donors. The breadth of HNO generation profiles from this donor class will allow continued analysis of the pharmacological effects of HNO and may facilitate the search for endogenous HNO. This chapter details the synthesis, structure, and mechanism of decomposition of the widely used HNO donor Angeli's salt as well as related compounds in the diazeniumdiolate class.
