Unusual thermal ring contraction of five‐membered cyclic azacarbodiphosphorane into a four‐membered 1,2 λ 5 ‐azaphosphete was observed (see scheme). Experimental and computational results indicate that the ring contraction results from a remarkable interconversion between two different types of divalent carbon species (dianionic and carbene): carbodiphosphorane and diphosphinocarbene.
