The light fantastic : Tungsten( 0 ) Fischer carbene complexes, previously considered to be photo‐inert, produce, by adequately choosing the ligands, three classes of photoproducts (see scheme). Thus, irradiation of tetracarbonyltungsten( 0 ) carbene complexes 1 leads to syn ‐metalated imines 2 , amino complexes 3 , and α‐amino esters 4 . Reasonable reaction pathways are proposed for all these processes.
