Carbonimidic dihalides (also known as isonitrile dihalides; typically dibromides or dichlorides) have recently attracted attention in their own right, not only as protecting groups for isonitriles, 2 but also as building blocks for more complex molecular architectures. 3 Carbonimidic dibromides can usually be prepared by simple addition of elemental bromine to the isonitrile. However, as noted in a seminal review, 4 the comparable addition of elemental ...
