1,3-diethenyl-1,1,3,3-tetraphenyldisiloxane - Introduction

Divinyltetraphenyldisilane, also known as DPEPS, is an organosilicon compound. Its chemical structure contains one silicon atom, four phenyl groups and two vinyl groups. The following is a description of the nature, use, preparation and safety information of DPEPS:

Nature:
-Appearance: DPEPS is a colorless or light yellow liquid.
-Solubility: It is soluble in organic solvents such as benzene, toluene and dichloromethane.
-Stability: DPEPS is relatively stable at room temperature, but it will react with oxygen in the air.

Use:
-Catalyst: DPEPS can be used as one of the ligands of transition metal catalysts in organic synthesis reactions.
-Silicone material: Because DPEPS contains silicon atoms in its molecular structure, it can be used to prepare silicone materials, such as silicone rubber and silicone oil.

Method:
- DPEPS can be prepared by the reaction of a vinyl compound and tetraphenyldisiloxane. The reaction is generally carried out under an inert atmosphere, such as a nitrogen atmosphere or an argon atmosphere.

Safety Information:
- DPEPS is irritating to skin and eyes, and should avoid contact with skin and eyes when using. In case of accidental contact, rinse immediately with plenty of water and seek medical help.
-When using DPEPS, maintain good ventilation and avoid inhaling gas or steam.
- DPEPS should be stored in a cool, dry place, away from fire and oxidizing agents.
