100-58-3 - Reducing agents for the preparation of metal carbonylates
In 1890, L.Mond discovered that when carbon monoxide burns after passing through the active metal nickel powder, it emits a bright green flame, and cools the obtained gas to obtain a colorless liquid (melting point 298K, boiling point 316K); If this gas flows through a heated glass tube, metal nickel is deposited on the tube wall. This gas is nickel tetracarbonyl Ni(CO)4. Since the 2060s, people have synthesized more than one hundred such carbonyl compounds and their derivatives, and almost all transition metals can form such compounds. This kind of special complex formed by transition metals and carbon monoxide ligands is called metal carbonyl compounds, or carbonyl complexes. Metal carbonyl compounds play an important role in modern inorganic chemistry, both in theoretical research and practical application.
The preparation of metal carbonyl compounds usually has the following methods:
(1) Direct synthesis. Most carbonyl complexes are made by the direct combination of metal and carbon monoxide, but the metal must be a new reduced product and be in a very activated state.
(2) Reductive carbonylation under high pressure. Using a reducing agent under high pressure, the metal and the carbonyl group undergo a carbonylation reaction. The reducing agents used are mainly hydrogen, active metals, phenyl magnesium bromide (C6H5MgBr), etc.
(3) Some polynuclear carbonyl compounds can be prepared by thermal decomposition or ultraviolet light decomposition.
(4) Two different metal carbonyl compounds interact to produce heteronuclear carbonyl compounds.

100-58-3 - Production method
The production method of phenyl magnesium bromide generally includes the following steps:
1. Preparation: First, the raw materials for benzene and magnesium bromide need to be prepared. Benzene can be obtained through the alkylation reaction of benzene, while magnesium bromide can be prepared through the reaction of magnesium bromide and ethanol.
2. Reaction: Mix benzene and magnesium bromide, and heat and stir at appropriate reaction temperature and time for substitution reaction. In this reaction, bromine ions replace the hydrogen atom in the benzene ring, forming phenyl magnesium bromide.
3. Termination of reaction: After the reaction is completed, an appropriate termination agent can be added to neutralize the remaining magnesium bromide or phenyl magnesium bromide to ensure a complete cessation of the reaction.
4. Separation and purification: After the reaction is completed, the solid product of phenylmagnesium bromide can be separated by filtration or extraction.
It should be noted that in actual production, it is also necessary to control the reaction conditions and operating methods to ensure the selectivity and yield of the reaction. In addition, phenylmagnesium bromide is generally used as an important intermediate in organic synthesis, which can further react to prepare more complex organic compounds.
