Abstract

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.
