Metallophosphination of Alkynes: Efficient Synthesis of β-Functionalized Alkenylphosphines
摘要:
Reactions of alkynes with [Cp2Zr(1-butene)(DMAP)] (DMAP = 4-(dimethylamino)pyridine) and chlorophosphines afforded zirconoalkenylphosphines in good to high yields, and their molecular structures were determined by single-crystal X-ray diffraction. The zirconoalkenylphosphines could be transformed into beta-functionalized alkenylphosphines through coupling reactions with various electrophiles in the presence of CuCl.
