BIS(INDENYL)DIMETHYLSILANE - Introduction
Dimethylbis(indenyl)silane, also known as DMBIS, with the chemical formula C20H20Si, is an organosilicon compound. Its properties are as follows:
1. Appearance: DMBIS is a colorless to light yellow liquid with a special smell.
2. Solubility: DMBIS is soluble in common organic solvents, such as ether, toluene and dichloromethane.
Uses of DMBIS include:
1. Catalyst: DMBIS can be used as a catalyst ligand and play a catalytic role in organic synthesis.
2. Synthesis intermediates: DMBIS can be used to synthesize other organosilicon compounds and precursors for preparing polymers and materials.
DMBIS preparation method:
The preparation methods of DMBIS are various. One common method is to react ferrocene and trichlorosilane to obtain DMBIS. The specific steps are as follows:
1. Under an inert atmosphere, add ferrocene and ferrous chloride together to a non-polar solvent, such as toluene or xylene.
2. Add excess trichlorosilane and heat the reaction, usually at 100-150 degrees Celsius.
3. After completion of the reaction, the solution was cooled and treated with dilute acid, from which the DMBIS product was obtained.
4. Finally, DMBIS is purified and isolated using a solvent, usually ether or alcohol.
Safety information about DMBIS:
1. Toxicity: DMBIS has low toxicity to humans, but it is still necessary to follow safe operating procedures.
2. ignition point and flash point: DMBIS is a flammable liquid, its ignition point and flash point need fire prevention measures.
3. Storage and handling: DMBIS should be stored in a cool, dry, well-ventilated place, away from fire and oxidant.
4. Waste treatment: It should be treated in accordance with chemical waste management regulations.
