Phenyl- and vinyllithiums having an alkyl substituent at their ortho- and cis-position, respectively, readily added to alkynes in the presence of 5 mol% of Fe(acac)(3). The reaction of o-(trimethylsilyl)phenyllithium with alkynes gave benzosiloles through an addition-cyclization sequence.
在5摩尔%Fe(acac)(3)的存在下,分别在邻位和顺位分别具有烷基取代基的苯基锂和乙烯基锂很容易添加到炔烃中。邻-(三甲基甲硅烷基)苯基锂与炔烃的反应通过加成环化序列得到苯并甲硅烷基。
