Abstract (AI)
We report the large scale syntheses and 'oxidative purification' of fcI(2), fcBr(2) and FcBr (fc = ferrocene-1,1'-diyl, Fc = ferrocenyl). These valuable starting materials are typically laborious to separate via conventional techniques, but can be readily isolated by taking advantage of their increased E(1/2) relative to FcH/FcX contaminants. Our work extends this methodology towards a generic tool for the separation of redox active mixtures.
Key Findings
1
Developed large-scale syntheses of fcI(2), fcBr(2), and FcBr (ferrocenyl halides).
2
Introduced an 'oxidative purification' method that isolates halogenated ferrocenes using their higher E(1/2) versus FcH/FcX contaminants.
3
Methodology is presented as a generic tool for separating redox-active mixtures.
4
Oxidative purification enables facile separation of otherwise hard-to-separate halogenated ferrocene mixtures compared to conventional techniques.
