Abstract
  • Reactions of alkynes with [Cp2Zr(1-butene)(DMAP)] (DMAP = 4-(dimethylamino)pyridine) andchlorophosphines afforded zirconoalkenylphosphines in good to high yields, and their molecular structureswere determined by single-crystal X-ray diffraction. The zirconoalkenylphosphines could be transformedinto β-functionalized alkenylphosphines through coupling reactions with various electrophiles in thepresence of CuCl.
