A novel compound with an unsaturated three‐membered ring , 2 H ‐1‐aza‐2‐phosphirene, is present in complex 1 . This unusual ligand is formed in a surprisingly simple way in the reaction of the corresponding amino(aryl)carbenepentacarbonyltungsten(0) complex with [bis(trimethylsilyl)methylene]chlorophosphane. The crucial step is the rearrangement of 2‐aza‐1‐phospha‐4‐tungsta‐1,3‐butadiene to give the 2 H ‐1‐aza‐2‐phosphirene tungsten complex.
