Isonitriles (A) are an important class of compounds because of the versatile reactivity of the functional group, enabling the preparation of numerous new compounds and natural products. Isonitriles can be converted to isonitrile dihalides (B), which represents a useful procedure for temporarily hiding the reactivity of an isonitrile (Tetrahedron Lett. 2012, 53, 4536-4537).
