摘　　要：A new type of ferrocenyl thia crown ethers used as selective ligands to some poisonous metals was synthesized, and the features of their mass spectra in electron ionization mode were summarized as: (1) the strong molecular ion peaks; (2) a characteristic homologous ion series with sequential loss of C 2H 4S or C 2H 4O from M C 5H 5; (3) a new rearrangement reaction of Fe migration; (4) the uncommon loss of alcohol or thiol from the fragments of Fe rearrangement. Some typical fragmentation patterns were discussed in detail with the aid of exact mass measurement and MS/MS technique.A new type of ferrocenyl thia crown ethers used as selective ligands to some poisonous metals was synthesized, and the features of their mass spectra in electron ionization mode were summarized as: (1) the strong molecular ion peaks; (2) a characteristic homologous ion series with sequential loss of C 2H 4S or C 2H 4O from M C 5H 5; (3) a new rearrangement reaction of Fe migration; (4) the uncommon loss of alcohol or thiol from the fragments of Fe rearrangement.
