| Questions And Answer | Back Directory | [Preparation]
Under anhydrous and oxygen-free conditions, dicyclohexylphosphine chloride was used as the starting material to obtain dicyclohexyldiethylaminophosphine through amino protection. Then, dicyclohexyldiethylaminophosphine reacted with diethylcadmium to obtain bis(dicyclohexylphosphine)cadmium intermediate, and finally reacted with dichloroalkanes to synthesize 1,2-BIS(DICYCLOHEXYLPHOSPHINO)ETHANE. |
