I(o)dide behind the wheel: Aromatic hypervalent iodine(III) compounds reacted with allyltrimethylsilane in the presence of a Lewis acid to give ortho‐allyliodoarenes through a reductive iodonio‐Claisenrearrangement (see scheme). An meta‐electron‐donating group in the λ3‐iodanes was indispensable to favor the [3,3]‐sigmatropic rearrangement over reductive elimination. The method was successfully used
