CAS:175136-62-6 | Tris[3,5-bis(trifluoromethyl)phenyl]phosphine

Tris[3,5-bis(trifluoromethyl)phenyl]phosphine is a special organic phosphine compound with strong electron-attracting properties, commonly used in organic synthesis and catalysis. The compound consists of a phosphorus atom and three 3,4-bis(trifluoromethyl)phenyl groups. It is soluble in organic solvents such as dichloromethane and toluene, and slightly soluble in water.

Features:

1. Strong electron-attracting effect: Due to the multiple trifluoromethyl groups on the benzene ring, tri[3,4-bis(trifluoromethyl)phenyl]phosphine has a very strong electron-attracting effect, making it a strong Lewis base (but weakly coordinated) phosphine ligand.
2. Good thermal stability: It has high thermal stability and is suitable for use under reaction conditions at higher temperatures.
3. Chemical inertness: Because of its stable electronic structure, it is inert to most chemical reagents.

Uses：

1. Widely used in organometallic catalytic reactions, such as cross-coupling reactions, to regulate catalytic performance by providing a special electronic environment.
2. Because of its strong electron-attracting ability, it can be used to research and develop organic electronic materials, such as organic light-emitting diodes and organic field-effect transistors.
3. Used to regulate reaction rates and selectivity in various organic reactions, especially those that are sensitive to the electronic environment.

1. This compound may cause irritation to the skin, eyes and respiratory tract.
2. Wear appropriate protective equipment such as gloves, goggles and protective masks during use or operation.
3. Follow good laboratory operating practices when handling this compound and ensure that there is a good ventilation system.
