An aromatic-antiaromatic switch in P-heteroles. A small change in delocalisation makes a big reactivity difference.
The low aromaticity of phosphole can be switched to low antiaromaticity by oxidizing the phosphorus atom. This subtle change in the mode of delocalisation alters substantially the chemical behaviour of these heteroles.
