Abstract

The transition metal complex C₆₀[Pd(PPh₃)₂] was prepared successfully in N₂ atmosphere free of water and oxygen and characterized by fourier transform infrared (FTIR), XPS and ¹³C NMR. The catalytic conversion of 1-heptene was investigated using this new complex as the catalyst. It was found that the complex C₆₀[Pd(PPh₃)₂] could actively catalyze the cyclization of 1-heptene into 1,2-dimethyl-cyclopentane. However, the complex Pd(PPh₃)₄ showed only the activities of hydrogenation and isomerization, instead of cyclization. It is believed that the cyclization of 1-heptene is contributing to the coordination of C₆₀ with Pd(PPh₃)₂, but that this coordination does not arise from the mechanical mixing of C₆₀ and Pd(PPh₃)₄.
