The readily available low-valent iron complex [Fe(CO)3NO]− catalyzes the efficient transfer of carbenes to isocyanides. The resulting ketenimines undergo in situ cyclocondensation with various bisnucleophiles to give a broad range of medicinally relevant heterocycles. A plausible mechanism for the carbene transfer is proposed based on DFT calculations.
