1-Amido-3-(1H)-1,2-benziodoxoles: Stable amidoiodanes and reagents for direct amidation of organic substrates
摘要:
Amidobenziodoxoles 2 can be prepared from benziodoxole 1, trimethylsilyltriflate and the appropriate amides in the form of stable, microcrystalline compounds. Amidobenziodoxoles 2 react with adamantane 3 or N,N-dimethylarylamines 5 to afford the corresponding products of amidation, 4 and 6. Copyright (C) 1996 Elsevier Science Ltd
unactivated secondary Csp3−H bond has been achieved using IrIII catalysts. The introduced N,N’‐bichelating ligand plays a crucial role in enabling iridium–nitrene insertion into a secondary Csp3−H bond via an outer‐sphere pathway. Mechanistic studies and density functional theory (DFT) calculations demonstrated that a two‐electron concerted nitrene insertion was involved in this Csp3−H amidation process
