Triolborates: water-soluble complexes of arylboronic acids as precursors to iodoarenes
摘要:
A facile synthesis of aryl and heteroaryl iodides from water-soluble complexes of aryl- and heteroarylboronic acids has been developed. (C) 2010 Elsevier Ltd. All rights reserved.
(NHC)-palladium complexes were found to be efficient nano-reactors for Suzuki-Miyauracross-couplingreactions of water soluble iodo- and bromoaryl compounds with cyclic triol arylborates at low temperature in water without any organic co-solvent. Combined with an improved one-step synthesis of triol arylborates from boronic acid, this remarkably efficient new tool provided a variety of 4′-arylated
