74507-64-5 - Introduction

Bis(pentamethylcyclopentadienyl)magnesium is an organic compound with the formula (C5Me5)2Mg, where C5Me5 represents a pentamethylcyclopentadiene group. It is a colorless or pale yellow solid, soluble in anhydrous ethers and chlorinated hydrocarbons, but less stable in air.

Bis(pentamethylcyclopentadienyl)magnesium are mainly used as reagents and catalysts in organic synthesis. It can react with a variety of organic halides to generate the corresponding organic magnesium compounds, which can be used to synthesize other organic compounds, such as alcohols, ketones, esters, etc. In addition, it can also be used as a catalyst in organic synthesis reactions, such as the formation of new carbon-carbon or carbon-hydrogen bonds.

A common method for preparing Bis(pentamethylcyclopentadienyl)magnesium is to react pentamethylcyclopentadiene with magnesium. The reaction can be carried out in the absence of a solvent or in an inert solvent and at a low temperature to avoid side reactions.

Regarding safety information, Bis(pentamethylcyclopentadienyl)magnesium needs to pay attention to its high flammability and water sensitivity during operation. It should be kept away from fire and moisture and used under protection. In addition, magnesium-related compounds have certain toxicity and irritation, so necessary safety measures should be taken when using them, such as wearing protective gloves, goggles and breathing equipment.
