Weis, Erik published the artcileIrIII-Catalyzed Selective ortho-Monoiodination of Benzoic Acids with Unbiased C-H Bonds, COA of Formula: C9H8O4, the publication is Chemistry – A European Journal (2020), 26(45), 10185-10190, database is CAplus and MEDLINE.
An iridium-catalyzed selective ortho-monoiodination of benzoic acids with two equivalent C-H bonds was presented. A wide range of electron-rich and electron-poor substrates underwent the reaction under mild conditions, with >20:1 mono/di selectivity. Importantly, the C-H iodination occurred selectively ortho to the carboxylic acid moiety in substrates bearing competing coordinating directing groups. The reaction was performed at room temperature and no inert atm. or exclusion of moisture was required. Mechanistic investigations revealed a substrate-dependent reversible C-H activation/protodemetalation step, a substrate-dependent turnover-limiting step and the crucial role of the AgI additive in the deactivation of the iodination product towards further reaction.
