Ferrocene (dicyclopentadienyliron) can be used: As a scaffold for chiral ligands in asymmetric catalysis.
Product details
Ferrocene is a crystal with orange needle-like structure that sublimates at temperatures higher than 100℃ and melts at 172.5-173℃. Its boiling point is 249℃. It is soluble in dilute nitric acid, concentrated sulfuric acid, benzene, petroleum and tetrahydrofuran and generates bluish fluorescence-containing deep red solution in dilute nitric acid and concentrated sulfuric acid. It is insoluble in water, 10% sodium hydroxide and hot concentrated hydrochloric acid, and it remains stable in air. Ferrocene has a strong property of UV absorbing and great thermostability, withstanding heating up to 470℃. It has a camphor-like scent and can be evaporated with water vapor. Ferrocene is neither dissolved nor decomposed in boiling solutions of these solvents.

The main differences between ferrocene and N-methylaniline
1. Application Fields
Ferrocene
Fuel additive: used as a combustion rate catalyst for gasoline or rocket propellants, improving combustion efficiency and replacing toxic tetraethyl lead-5.
In the field of medicine, derivatives are used to treat anemia, tumors, and applied in photodynamic therapy.
Environmental Protection and Materials: Catalytic treatment of pollutants to improve the performance of polymer materials.
N-methylaniline
Pesticide synthesis: used for the production of insecticides and herbicides such as thiamethoxam and methyl herbicide.
Dyes and Chemicals: Used as dye intermediates (such as cationic brilliant red FG) and rubber additives.
Fuel improvement: increase gasoline octane rating, but with limited usage and control of residual 16.
2. Synthesis method
Ferrocene
Chemical synthesis method: Sodium cyclopentadienyl reacts with ferrous chloride to form ferrocene 3; Alternatively, electrolysis can be used to reduce cations through an iron plate electrode and combine them with cyclopentadiene.
Raw materials and conditions: Cyclopentadiene, iron powder or ferrous chloride are required, and the reaction often requires nitrogen protection and high temperature (such as 300 ℃).
N-methylaniline
Aniline methylation: Aniline reacts with methanol over copper zinc chromium catalyst or sulfuric acid catalyst to produce crude product, which is then distilled and purified.
Laboratory synthesis: Using dimethyl sulfate as a methylating agent, product 6 was separated through stepwise acid-base treatment.
3. Raw materials
Ferrocene:
The core raw materials are cyclopentadiene (C ₅ H ₆) and iron sources (such as iron powder and ferrous chloride) 37.
The auxiliary materials include solvents such as tetrahydrofuran and diethylamine.
N-Methylaniline:
The basic raw materials are aniline (C ₆ H ₅ NH ₂) and methylation reagents (such as methanol, dimethyl sulfate).
Catalysts commonly used include copper, zinc, chromium, or phosphorus trichloride.
4. Packaging method
Ferrocene:
Sealed moisture-proof packaging (such as aluminum foil bags or galvanized drums) is usually used to avoid contact with oxidants, and it should be labeled as "flammable solid" 57.
N-Methylaniline:
Commonly used dark glass bottles or plastic drums for packaging, should be stored away from light and labeled as "toxic" to prevent volatilization and oxidation
