Cyclic amino compounds known as N-hetero­cyclic carbenes (NHCs) are among the most versatile and popular ligands for stabilizing transition-metal catalysts. NHCs come in many flavors: The rings vary in size from three to eight atoms; include up to three nitrogen atoms and two carbenes per ring; and sometimes contain boron, phosphorus, or other heteroatoms. The latest version, created by Holger Braunschweig and coworkers of the University of Würzburg, in Germany, is a . . .
