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
