Regio- and Stereoselective Synthesis of 1,5-Dienes Using Allylic Barium Reagents

Article abstract of DOI:10.1246/bcsj.68.1263

The highly α,α' selective and sterocontrolled homocoupling reaction of allylic halides was achieved using barium reagent.The double-bond geometry of the starting allylic chloride was completely retained.The α,α' cross-coupling products were also prepared stereospecifically and regioselectively by this method.
