Witryna13 lut 2024 · 1 Answer Sorted by: 2 One factor: since ferrocene is covalently bonded, the rings "communicate" with each other via the molecular orbitals passing through the iron atom. Thus the acetyl group placed on one ring not only deactivates that ring, but to some extent deactivates the second ring as well. Witryna21 cze 2024 · One way to resolve these problems is through Friedel-Crafts Acylation. Also, the reaction will only work if the ring you are adding a substituent to is not deactivated. Friedel-Crafts fails when used with compounds such as nitrobenzene and other strong deactivating systems.

WitrynaDay 2 - Purification of Ferrocene and Acetylation of Ferrocene. Ferrocene is a crystalline, diamagnetic material that is extremely stable to air, moisture and light. It is moderately to extremely soluble in practically all-nonpolar or weakly polar solvents. It may be purified by sublimation. Weigh and take a mp of the dried crude ferrocene. camping car hymer 1995
