Research Article demonstrates a unique rearrangement method enabling dual functionalization of alkenyl iodanes at low temperatures.
In the Research Article e26108, Yuchen Liang, Bo Peng, and co-workers report an aliphatic iodonium‑Claisen rearrangement that features two defining characteristics: an exceptionally low reaction temperature (−78 °C) and an ultrafast timescale (completed within 74 ms). These unconventional features enable the formation and interception of highly unstable iodonium intermediates, thereby achieving dual functionalization of alkenyl iodanes.
