Copper catalysis allows the direct oxygen alkenylation of dialkyl phosphonates with alkenyl(aryl)iodonium salts with selective transfer of the alkenyl group. This novel methodology proceeds with a wide range of phosphonates under mild conditions and gives straightforward access to valuable enol phosphonates in very good yields.

铜催化膦酸酯的O-烯基化

铜催化作用允许二烷基膦酸酯与烯基（芳基）碘鎓盐直接进行氧烯基化，并选择性地转移烯基。这种新颖的方法可以在温和的条件下使用多种膦酸酯，并以非常高的收率直接获得有价值的烯醇膦酸酯。
