资源简介：
A metal-free electrophilic
phosphination reaction has
been developed. Electrophilic phosphorus species generated in situ from secondary phosphine oxides and Tf2O smoothly couple with alkynes possessing pendant nucleophiles
to afford the corresponding phosphinated cyclization products
in good yield. Preliminary NMR studies show that phosphirenium
species may be involved as intermediates of the cyclization
reactions.
