| | Bis(benzonitrile)dichloroplatinum(II) Usage And Synthesis |
| Uses | Bis(benzonitrile)dichloroplatinum(II) is used as a catalyst for asymmetric hydroformylation reactions, allylation reactions, cyclopropanation reactions, hydrosilylation reactions and carbene insertion into O-H bonds of alcohols. | | Preparation | Bis(benzonitrile)dichloroplatinum(II) can be prepared as a mixture of cis and trans complexes. The reaction of Palladium(II) Chloride in benzonitrile at room temperature for 7 h yields a mixture that can be separated chromatographically to yield 26% trans- and 58% cis-PtCl2(PhCN)2. An alternate route requires stoichiometric amounts of potassium tetrachloroplatinate(II) and benzonitrile stirred at room temperature for one week. Trituration of the product with hot benzene yields pure cis-PtCl2(PhCN)2 in 60% yield; the cooled benzene solution yields pure trans-PtCl2(PhCN)2 in 20% yield. | | Purification Methods | chromatography on silica gel with dichloromethane as eluant, or trituration with hot benzene. |
