2‐Phosphaethynolates, particularly the sodium salts, Na(OCP), are exceedingly versatile nucleophiles, which renders these species important as precursors to phosphorus‐containing π‐conjugated heterocycles. Moreover, the 2‐phosphaethynolate anion serves as a potent phosphide transfer reagent giving rise to the first stable phosphinidine among other products. First studies also make evident that the phosphaethynolate ion serves as a fascinating ligand in coordination chemistry. Sodium salts of the long sought arsenic‐containing analogue, 2‐arsaethynolate, were synthesized only recently allowing the formation of arsenic‐based element organics and coordination compounds.
