Interaction of Cyclopropane with Platinum-Metal Chlorides under Carbon Monoxide Pressure in Benzene

Article abstract of DOI:10.1021/jo01289a027

The six platinum-metal chlorides were reacted with cyclopropane in benzene under carbon monoxide pressure to produce propyl benzenes and, in three instances, chlorobutyrates.The isomer of propylbenzene obtained ranged from pure n-propylbenzene from PdCl2 to pure isopropylbenzene for OsCl3 and IrCl3.The other three platinum-metal chlorides gave mixture of the two propylbenzenes.The reaction was shown to be specific for benzene and cyclopropane as chlorobenzene and toluene failed to enter into the reaction.Likewise, methylcyclopropane did not react with benzene to produce butylbenzenes.
