双五苯基环戊二烯基钴的合成

The Syntheses of Decaphenycobatlocene

用五苯基环戊二烯为原料， 与Ｋ、Ｎａ 和ｎ － ＢｕＬｉ 反应生成五苯基环戊二烯基碱金属盐， 再分别与二氯化钴反应， 合成双♂五苯基环戊二烯基′钴， 产率５０ ％ 。另外用高活性的金属钴与五苯基环戊二烯反应， 得到了标题化合物。并且用原子吸收、红外、紫外、质谱和元素分析作了鉴定。

Pentaphenylcyclopentadienyl salts are synthesized by the reaction of pentaphenylcyclopentadiene with n-BuLi,Na and K,respectively. The (ph 5C 5)-anion reacts with CoCl 2 in toluene solvents to form the compound(η 5-ph 5C 5) 2Co(4) in above 50% yield.In addition,high active metal Co reats with pentaphenylcyclopentadiene to give the compound(4). The product is characterized by AAS,IR、UV、MS and elemental anatysis.
