A detailed study for the generation of nitric oxide (NO) upon reaction a binuclear Ni(II)-bis(ONO) complex with carboxylic acids (RCOOH, R = Me, Ph), thiols (RSH, Ph, p-F-C6H4), benzeneselenol (PhSeH), thiocarboxylates (RC(O)S-, thiocarboxylic (RC(O)SH, and acid chlorides (RC(O)Cl, Ph) has been presented. The reactions thiols/selenols give access to unusual dinickel(II)-nitrito-thiolato/selenolato complexes, while RC(O)S-, RC(O)SH, RC(O)Cl offer new mechanistic insights into perthionitrite (SSNO-) O-nitrosyl carboxylates (RC(O)ONO), well-known NO-carrying species in biology. Interestingly, RC(O)S- involved nucleophilic attack latter coordinated NO2- generate SSNO-, proceeds via hitherto unknown carbonyl carbon RC(O)ONO, which, turn, produces NO. present comparative thus demonstrates metal-coordinated investigations supported by molecular structure determinations spectroscopic studies establishes nitrite be highly efficient method NO excellent yield.
