Preparation of metal carbonyl compound can usually via the following methods:
1. Direct synthesis. Most metal carbonyl complexes are prepared by direct combination between metal and carbon monoxide. However, the metal must be new reduction products, and is in a very activated state.
2. Reduction carbonylation effect at high pressure. Apply reducing agent under high pressure to enable the carbonylation reaction between the metal and carbonyl group with the major reducing agents mainly including hydrogen, active metals, phenylmagnesium bromide (C6H5MgBr) and so on.
3. With thermal decomposition or UV irradiation decomposition, we can obtain certain polynuclear carbonyl compounds.
4. Two different kinds of metal carbonyl compounds can interact with each other to give hetero-nuclear carbonyl compound.

4. Take tetrahydrofuran as the solvent, have phenylmagnesium bromide reacted with germanium tetrachloride to obtain tetraphenyl germane.
5. It can be obtained through the low-temperature reaction between lead chloride and phenylmagnesium bromide (Or phenyllithium) in the presence of iodobenzene to derive tetraphenyl lead.
6. Sodium tetraphenylborate is mainly used for the determination of potassium ion, ammonium ion, rubidium ion and cesium ion. It can be obtained with the following process: phenylmagnesium bromide is interacted with boron trifluoride/diethyl ether to generate Tetraphenylboron magnesium bromide first. Evaporate the diethyl ether; add water and then used the calculated amount of sodium carbonate for treatment to obtain it.

Phenylmagnesium Bromide is a reagent used in the preparation of arylcarbonimidic dichlorides via dichloroiodobenzene-mediated gem-dichlorination of aryl isonitriles.
Phenylmagnesium bromide, with the simplified formula C 6H 5MgBr, is a magnesium-containing organometallic compound. It is commercially available as a solution in diethyl ether or tetrahydrofuran (THF). Phenylmagnesium bromide is a Grignard reagent. It is often used as a synthetic equivalent for the phenyl "Ph−" synthon.
