Abstract

original image

Two-headed carbenes: N-heterocyclic carbene complexes of rhodium and iridium were obtained by the double C[BOND]H activation of CH2 groups in N heterocycles (see structure: C gray, N blue, Cl green, Ir pink). The reaction constitutes a valuable approach to new carbene ligands with unprecedented architectures.
