one-pot sequential reaction of Me3SnC≡CSiMe3 first with an alkenyl iodide R1I and secondly with another alkenyl (or aryl) iodide R2I in the presence of newly added (Et2N)3S+ Me3SiF2− affords conjugated dienynes R1-C≡C-R2 with high stereospecificity.
钯催化的一锅煮的Me连续反应3 SnC≡CSiMe 3第一与链烯基碘- [R 1 I和其次与另一链烯基(或芳基)碘- [R 2我在新添加(ET的存在2 N)3小号+我3的SiF 2 - ,得到共轭dienynes - [R 1 -C≡CR 2具有高的立体定向性。
