Abstract
Electrospray ionization (ESI) enables the detection of highly unstable silver(III) complexes prepared in situ from the dicarboxamide ligand L (where L = N,N'-bis(2,6-diisopropylphenyl)-2,6- pyridinedicarboxamide) and Ag(CH(3)COO). The collision-induced dissociation of [Ag(III)(L-H)(CH(3)COO)](+) leads to the elimination of oxiranone. As well as the silver(III) complexes, various other silver(I) complexes generated in the positive as well as negative ionization mode were investigated.
