Rac-(Dimethylsilylene) Bis (2-Methyl-4-Phenylindenyl) Zirconium Dichloride - Introduction
Dimethylsilylbis (2-methyl-4-phenylindenyl) zirconium dichloride is an organometallic compound with the chemical structure [Rac-(CH3)2Si(2-Me-4-PhInd) 2ZrCl2]. The following is its nature, use, preparation and safety information:
Nature:
-Appearance is a white to pale yellow solid.
-Relatively stable at room temperature, but need to be stored under anhydrous conditions.
-Soluble in common organic solvents such as toluene, dichloromethane and ether.
Use:
-Dimethylsilylbis (2-methyl-4-phenylindenyl) zirconium dichloride is a commonly used indenyl filler compound, which is widely used in the field of homogeneous catalysts and asymmetric synthesis.
-It can be used for many important organic synthesis reactions, such as asymmetric catalytic hydrogenation, asymmetric mush tree ketone synthesis, asymmetric epoxidation, etc.
Preparation Method:
The preparation method of dimethylsilylbis (2-methyl-4-phenylindenyl) zirconium dichloride usually involves the following steps:
1.2-methyl -4-phenyl indenyl borate reacts with bromoacetate in an inert solvent to generate the corresponding bromide.
2. The iridium catalyst is synthesized, and the bromide in step 1 is iodinated to generate the corresponding iodide.
3. The iodide in step 2 is reacted with dimethylmagnesium silicide to generate dimethylsilylbis (2-methyl-4-phenylindenyl) magnesium compound.
4. Finally, the magnesium compound in step 3 is reacted with zirconium chloride to produce the final product dimethylsilylbis (2-methyl-4-phenylindenyl) zirconium dichloride.
Safety Information:
Dimethylsilylbis (2-methyl-4-phenylindenyl) zirconium dichloride is not significantly hazardous under normal conditions of use. However, due to the organometallic compounds, it is still necessary to take appropriate safety measures:
-Avoid direct contact with skin, eyes and respiratory tract.
-Avoid swallowing or ingestion.
-Ensure good ventilation during use.
-Store away from fire and oxidant.
