Synthesis of acetylferocene

From their structures, the number and multiplicity of peaks in the NMR spectrum for each compound can be predicted. Each compound produces a unique spectra, thus each can be identified. Acetic anhydride with phosphoric acid was used to acetylated ferrocene as opposed to the more common reagents used in a Friedel-Crafts reaction of aluminium chloride with acetyl chloride in DCM because, with acyl chloride, the tendency is to over-react to the diacetylated form, and the solvent is much more harmful. Acetylation with acyl chloride also requires anhydrous conditions for a successful reaction, which is not required when using acetic anhydride [7].

Organic Teaching Lab The purpose of this site is to serve as a clearinghouse for new experiments that are suitable for the undergraduate laboratory course.

Even if your experiment is published, for instance in the Journal of Chemical Education, we would encourage you to post it here also. We hope that this site will serve two purposes: The classical Friedel-Crafts acetylation of ferrocene has been updated to include silica gel TLC and column chromatography.

Abstract: The solvent effect on the position of the carbonyl vibrational stretching of acetylferrocene in aprotic media was studied in this work. The solvent-induced shifts in this organometallic compound were interpreted in terms of the alternative reaction field model (SCRF-MO) proposed by Kolling.

Ferrocene will be acetylated by the action of phosphoric acid* and acetic anhydride*. The number of products in the reaction mixtures will be determined by thin- layer chromatography and the products isolated by column chromatography.

Acetylation Reaction. Place a 3x10 mm stir bar in a 10 mL round bottom flask (RBF). water must be removed from the system because the grignard reagent will pluck a hydrogen off water and create Mg(OH)Br and some alkyl group.

Synthesis and Reactions of Ferrocene The archetypal organometallic compound ferrocene, [Fe(η-C 5 H 5) 2 ], is of historical importance since its discovery and structural characterisation in the early s sparked extensive research into the chemistry.

Cross-Corresponding Preparation of Organometallic Acetylferrocene The formation mechanism of the acetylferrocene micro-nanomaterials is also proposed. This work provides a new strategy for the material synthesis and preparation and may realize the reuse of organometallic materials.
