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.

2-磷酸和2-芥子油酸酯–现代合成化学中的通用构建基块

2-磷酸乙炔酸酯，尤其是钠盐Na（OCP）是用途广泛的亲核试剂，这使得这些物种作为含磷π共轭杂环的前体非常重要。此外，2-膦基胸苷酸根阴离子可作为有效的磷化氢转移试剂，在其他产品中产生第一个稳定的膦亚胺。最初的研究还表明，磷胸苷酸根离子在配位化学中充当了引人入胜的配体。一直以来，人们一直在寻求含有砷的类似物2-二十碳三烷基硫酸钠的钠盐，这种钠盐允许形成基于砷的元素有机物和配位化合物。
