31277-98-2 - Reference Information
| Application | Bis (1, 2-bis (diphenylphosphine) ethane) palladium is mainly used as a catalyst in organic synthesis reactions. It can be prepared by heating 1, 2-bis (diphenylphosphine) ethane and palladium dichloride in DMSO. It has been reported in the literature that bis (1, 2-bis (diphenylphosphine) ethane) palladium is used to prepare fullerene pyrrole metal complexes (PyrC60)-Pd(dppe). |
| use | bis (1,2-bis (diphenylphosphine) ethane) palladium is a precious metal organic substance and can be used as a catalyst containing palladium. |
| preparation | under the protection of nitrogen, 0.2 gPdCl2,1.12gPh2PCH2CH2PPh2 and 12ml dimethyl sulfoxide are mixed and heated to 140 ℃ to make them into a uniform solution. at this time, the solution is light red, the oil bath is removed, stirred intensely for 30min, then 0.3ml(0.226g) hydrazine hydrate is slowly added dropwise, the reaction is intense, nitrogen is generated, and the solution turns dark brown, cooling in a water bath, precipitating brown crystals at about 125°C, slowly cooling to room temperature, centrifuging, washing twice with 5ml of ethanol and 5ml of ether, and vacuum drying to obtain orange crystals with a yield of about 78.2%. |
