软硬酸碱原理可应用于解释α-卤代酮的一些还原脱卤反应。例如,碘负离子(软路易斯碱)和某些硬路易斯酸,如三氯化铝、三氯化铁、三氟化硼、三价铈和质子酸等的复合作用对α-卤代酮的脱卤。在三碘化铈或者三氟化铈/碘化钠等作用下,使α-卤代酮脱
The hard and soft acid-base principle can be applied to explain some reductive dehalogenation reactions of α-halo ketones. For example, the combination of iodine anion (soft Lewis base) and certain hard Lewis acids such as aluminum trichloride, ferric chloride, boron trifluoride, trivalent cerium and protonic acid, etc., halogen. In cerium iodide or cerium trichloride / sodium iodide under the action of the α-halo ketone off
