Synthesis of C_(60)[Pd(PPh_3)_2] and Study on Its Catalytic Performance for Hydrogenation of 1-Heptene

在无水无氧氮气保护的条件下，制备Ｃ_（６０）的过渡金属络合物Ｃ_（６０）［Ｐｄ（ＰＰｈ_３）_２］，对其进行了表征．以此新络合物为催化剂，研究它对１－庚烯氢化反应的催化性能．结果表明，Ｃ_（６０）［ｐｄ（ＰＰｈ_３）_２］具有使１－庚烯环化生成１，２－二甲基环戊烷的独特催化活性．

In this work we prepared palladium complex of C6o in nitrogen atmosphere free of water and oxygen, which was characterized and used as catalyst for the hydrogenation of 1-heptene. The results show that the complex C60[Pd(PPh3)2] has unique catalytic activities in cyclizing 1-heptene to 1,2- dimethylcyclopentane. For classical metal palladium complexes, they only exhibit alkylation and double bond isomerization activities in the hydrogenation of olefin but no cyclization. The results also suggest that the catalytic activities come from the complex, not from the mechanical mixture of C60 and Pd (PPh_3)_4.
