The reaction of σ-vinylpalladium complexes with alkyllithiums. Stereospecific syntheses of olefins from vinyl halides and alkyllithiums

Masaaki Yamamura; Ichiro Moritani; Shun-Ichi Murahashi

Abstract Vinyl halides react with alkyllithium compounds in the presence of tetrakis(triphenylphosphine)palladium to give olefins stereospecifically in excellent or fairly good yields. When less reactive Grignard reagents are employed instead of alkyllithium compounds, these reactions can be carried out catalytically with palladium.
