    Nomenklatur

    Der angezeigte Name Diphenylphosphinsäure-ethylester für die o.a. Verbindung ist inkorrekt, der korrekte (englische) Name führt aber in der Suche zur richtigen Struktur. Auf Deutsch heißt die Verbindung Diphenylphosphinigsäureethylester. Diphenylphosphinsäureethylester hat die Formel Ph2POOEt (ein Sauerstoffatom mehr).
