(CDI)-promoted generation of CO from formic acid has been exploited in a reductive formylation of aryl iodides in the presence of tris(dibenzylideneacetone)dipalladium. The reaction conditions are mild with a broad functional-group tolerance that includes keto, bromo, nitrile, ester, and nitro groups. In the reaction pathway, CDI reacts with formic acid to generate a formyl imidazole that ultimately
羰基二咪唑 (CDI) 促进甲酸生成 CO 已被用于在三(二亚苄基丙酮)二钯存在下芳基碘化物的还原甲酰化。反应条件温和,具有广泛的官能团耐受性,包括酮基、溴基、腈基、酯基和硝基。在反应途径中,CDI 与甲酸反应生成甲酰咪唑,最终在活化的芳基钯络合物上产生甲酰化过程所需的 CO。
