The diiridium( II ) complexes 2 (X = CH 3 , CH 2 I) are not intermediates of alkylidene‐bridged complexes but are stable compounds. The notable acceleration of the synthesis 1 → 2 by light suggests a radical mechanism, but the formation of a mixture of chloro‐, bromo‐ and iodocomplexes in the synthesis with CH 2 I 2 in the presence of [Bu 4 N]Br and CH 2 Cl 2 is quite contradictory thereto.
