The rational formation of element–element bonds is one of the key concerns in synthetic chemistry. Boron–boron bonds are usually generated by reaction of a halo‐borane with a reducing agent. This work reports on the formation of boron–boron bonds by reaction of a hydrido‐borane with the oxidizing agent iodine, being a seemingly paradoxical approach. The “magic effect” of iodine (I 2 ) is highlighted in the artwork. A combined experimental and theoretical analysis shows that the boron–boron bond results from a dehydrocoupling step.
