Palladium-catalyzed cyclization and cross-coupling of acetylenic aryl triflates with organotin reagents

Article abstract of DOI:10.1016/0040-4039(91)80570-V

Acetylenic aryl triflates reacted readily with vinyltributyltin, allyltributyltin, 1-(trimethylsilyl)-2-(tributylstannyl)acetylene, and trimethylsilyltributyltin in the presence of a palladium catalyst to produce (Z)-indanylidene and (Z)-tetralinylidene substituted compounds, the stereospecificity of the reactions for the synthesis of these compounds being ≥98%.
