Studies on cyclomercuration of bisferrocenylimines
摘要:
Cyclomercuration of bisferrocenylimines [(eta(5)-C5H5)Fe{(eta(5)-C5H4)-CR=N-(C6H3-2-R')}](2), (R=H, CH3; R'=H, CH3, Cl) occurred predominantly in the ortho-position of the substituted ferrocenyl ring to yield double 2-mercurated ferrocenylimines, which arise from activation of two sigma(C-sp2,C-ferrocene-H) bonds. The composition and structure of the metallocycles were characterized by elemental analysis, IR, H-1 NMR and 2D C-13{H-1}-COSY spectra, which confirmed the existence of two five-membered mercuriocycles fused with the ferrocenyl moieties.
