Organo-tin compoundsS 4800 Regio- and Stereoselective Hydrostannation of Allenes Using Dibutyliodotin

Hydride (Bu2SnIH) and Successive Coupling with Aromatic Halides. — Highly regio- and stereoselective hydrostannation of allenes affords α,β-disubstituted vinyl-tins. Their direct coupling with PhI provides an efficient one-pot access to multi-sub-stituted alkenes [cf. (VI), (VIII)]. — (HAYASHI, N.; KUSANO, K.; SEKIZAWA, S.; SHIBATA*, I.; YASUDA, M.; BABA, A.; Chem. Commun. (Cambridge) 2007, 46, 4913-4915; Res. Cent. Environ.
