Stereospecific Synthesis of Vinyl(phenyl)iodonium Tetrafluoroborates via Boron-Iodane Exchange of Vinylboronic Acids and Esters with Hypervalent Phenyliodanes
摘要:
Reaction of vinylboronic acids and esters with hypervalent phenyliodanes in the presence of BF3-Et2O undergoes boron-iodane exchange at O degrees C in dichloromethane yielding vinyl(phenyl)iodonium tetrafluoroborates stereoselectively with retention of configuration. (C) 1997 Elsevier Science Ltd.
