Synthesis and electrochemistry of ferrocenyldiazabutadiene metal carbonyl complexes (Fc-DAB)M(CO)(4) [M = Cr,Mo,W]

摘要

The synthesis, characterization (UV-Vis, IR, MS, NMR), and electrochemistry (CV, DPV) of ferrocenyl diazabutadienes and their chromium, molybdenum, and tungsten tetracarbonyl complexes are reported in this study. The properties of these compounds are compared to those of p-methoxyphenyl diazabutadiene analogues, (a) allowing the clear distinction between ferrocene-based and diazabutadiene metal carbonyl localized redox processes in these multimetallic complexes, and (b) showing that the electronic interaction between the peripheral ferrocenyl substituents increases upon complexation to the Group 6 transition metal tetracarbonyl moieties.
