BIS(TRICYCLOHEXYLPHOSPHINE)PALLADIUM(II) DICHLORIDE - Reference Information
| Introduction | Dichlorodi (tricyclohexyl) palladium is a common complex of palladium catalysts and phosphine ligands, and its appearance is yellow at room temperature and pressure Solid powder. Dichlorobis (tricyclohexyl) palladium has moderate solubility in halide solvents such as dichloromethane and chloroform, but it is soluble in benzene, toluene, but insoluble in water, alcohol solvents, acetone, and ethyl Ether, petroleum ether and n-hexane. |
| Uses | Dichlorobis (tricyclohexyl) palladium is used as a common catalyst in the molecular synthesis of important drugs in organic synthesis, especially in Suzuki coupling It has a very wide range of applications. Interestingly, sometimes the palladium catalyst and tricyclohexylphosphine are prepared into a complex in advance. The catalytic effect of the coupling reaction is better than that of adding these two compounds directly to the reaction solution. It may be the catalyst complex prepared in advance. The coordination of metal palladium and multiple phosphine ligands can be avoided. In addition, there are related reports that the synthesis of other palladium catalyst species can be carried out with dichlorobis (tricyclohexyl) palladium as the parent. |
| synthesis method | tricyclohexylphosphine and palladium dichloride are stirred in acetone solvent for several hours. After the reaction is over, the solid is filtered out as the target product dichlorobis (tricyclohexyl) palladium. The separated product is best stored in an inert gas atmosphere in a container such as a glove box to prevent tricyclohexylphosphine from being oxidized. |
| Environmental hazards | Dichlorodi (tricyclohexyl) palladium, as an organic compound containing both halogen and heavy metals, is more harmful to the water environment. Undiluted or a large number of products should not be allowed to contact groundwater, waterways or sewage systems. |
