Regio- and stereoselective hydrostannation of allenes using dibutyliodotin hydride (Bu2SnIH) and successive coupling with aromatic halides

Regio- and stereoselective hydrostannation of allenes by using di-n-butytliodotin hydride (Bu2SnIH) was accomplished to give alpha,beta-disubstituted vinyltins, which induced the synthesis of multisubstituted alkenes in a one-pot procedure.
