2-Phosphaethynolates, particularly the sodium salts, Na(OCP), are exceedingly versatile nucleophiles, which renders these species important as precursors to phosphorus-containing -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.
