Simple and efficient palladium-catalyzed carbonylation of iodoxyarenes in water under mild conditions
摘要:
Iodoxyarenes (ArIO2) readily react with CO (1 atm) in water, in the presence of Na2[PdCl4] (0.1%) and Na2CO3 at 40-50-degrees-C, to give the corresponding carboxylic acids, ArCOOH, in 55-89% isolated yield. Particularly attractive features of the reaction are that, unlike most iodoarenes, ArIO2 can be carbonylated in aqueous media without any organic solvents, due to their solubility in water and high reactivity.

substrate oxidation reactions. Recently we disclosed the aerobic synthesis of I(III) reagents by intercepting reactive oxidants generated during aldehyde autoxidation. In this work, aerobicoxidation of iodobenzenes is coupled with disproportionation of the initially generated I(III) compounds to generate I(V) reagents. The aerobically generated I(V) reagents exhibit substrate oxidation chemistry analogous
