2 H ‐Imidazol‐2‐ylidene, readily obtained by the photolysis of matrix‐isolated 2‐diazo–2 H ‐imidazole , should be regarded as a strained cumulene rather than a carbene. It undergoes photolysis to give N ‐cyano‐1 H ‐azirene (shown here). The reactive intermediates were investigated with matrix‐isolation spectroscopy.
