Treatment of 1-alkynylphosphine with magnesium dlalkylcuprate in ether results in regio- and stereosetective syn-csrbocupration. The alkenyicopper Intermediate reacts with electrophile, which leads to allylation, acylation, and phosphination. The phosphinatlon offers a new route to gem-diphosphinoaikene, an interesting phosphorus-based organic structure.
