STEREOSELECTIVE SYNTHESIS OF (E,E)-1-ARYLSELENOBUTADIENES BY CROSS-COUPLING REACTIONS IN THE PRESENCE OF PALLADIUM CATALYST

摘要

Hydrozirconation of arylselenoethynes 1 gives selenium-containing zirconium(TV) complexes 2, which are cross-coupled with alkenyl halides in the presence of Pd(PPh(3))(4) to afford (E,E)-1-arylselenobutadienes 4 in high yields. Copyright (C) 1996 Elsevier Science Ltd [References: 16]
