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.
