| 摘 要： | The intermediates of the Appel coupling reagents were studied in acetonitrile, dimethoxyethane and dioxane by ^31p NMR, ^13C NMR spectrum and ESI-MS. In dioxane a new high coordinated phosphorous compound with ^31p NMR shift at -39 ppm was observed. The ESI-MS showed that it could be a penta-coordinated phosphorous compound containing dioxane. The carboxyl activated intermediates were also studied in three solvents.

| Abstract: | The intermediates of the Appel coupling reagents were studied in acetonitrile, dimethoxyethane and dioxane by P NMR, C NMR spectrum and ESI-MS. In dioxane a new high 31 13 coordinated phosphorous compound with P NMR shift at -39 ppm was observed. The ESI-MS 31 showed that it could be a penta-coordinated phosphorous compound containing dioxane. The carboxyl activated intermediates were also studied in three solvents. |
