摘要： 本文研究了苯基锂和对、间、邻甲苯基锂及对、邻甲氧苯基锂与6,6-二烷基富烯环外双键加成反应的立体效应。在室温下于乙醚溶剂中,6,6-二烷基富烯同上述芳基锂反应,形成取代环戊二烯基锂,经水解给出含或不含手性碳的叔烷基环戊二烯。

关键词: 二烷基富烯, 芳基锂, 加成, 环戊二烯

Abstract: A Series of substituted cyclopentadienes, namely, C5H5RR'Ar,R = CH3, R' = CH3, C2H5, C3H2, CH2CH(CH3)2, R = R' =C2H5; R = R' = (CH2)5; Ar = C6H5, p-, m-, o-CH3C6H4 , .p-,o-CH3OC6H4 were prepared by the reaction of 6,6-dialkylfulvenes with aryllithium followed by treatment with water. For the steric effect of o-tolyl and o-methoxyphenyl, the chemical shifts of alkyl protons at 6-position in o-substituted phenyl cyclopentadienes split to two groups of signals.

Key words: Dialkylfulvene, Aryllithium, Addition, Cyclopentadiene
