Dibenzylideneacetone synthesis
WebAbstract. A carbonyldiimidazole (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.
