Carbocupration of 1-Alkynylphosphines Followed by Trapping with Electrophiles
摘要:
Treatment of 1-alkynylphosphine with magnesium dialkylcuprate in ether results in regio- and stereoselective syn- carbocupration. The alkenylcopper intermediate reacts with electrophile, which leads to allylation, acylation, and phosphination. The phosphination offers a new route to gem-diphosphinoalkene, an interesting phosphorus-based organic structure.
