Complex formation of silver(i) ions with a glucosinolate derivative: structural and mechanistic insights into myrosinase-mimicking C–S bond cleavage

Abstract

The crystal structure of an unprecedented silver complex of O-acetylsinigrin has shown chelating bonds of the sulfated thiohydroximate and an η²-bond of the ethylene moiety with Ag(I). Mechanistic studies on the formation and decomposition of the complex by the ¹H NMR measurements and theoretical calculations with the DFT method indicated relevance to the glucosinolate degradation in biological systems.
