Abstract

Die Autoren dieser Zuschrift mçchten einen weiteren Autor aufnehmen: Dr. Willem Schipper, Thermphos International B.V., Vlissingen (Niederlande) Dr. Schipper trug durch Diskussionen und die Interpretation erster elektrochemischer Resultate entscheidend zu dieser Verçffentlichung bei. Außerdem machte er wichtige Vorschläge für die Charakterisierung der ansonsten nicht fassbaren Zielverbindung.

High‐Pressure Chemistry of Red Phosphorus and Water under Near‐UV Irradiation

“…These bands can be tentatively explained with the presence of H 3 PO (phosphine oxide) and PH 2 OH (phosphinous acid) species, which may form as metastable intermediates along the stepwise hydrolytic disproportionation of phosphorus. [30] Despite the lack of Raman spectra of such species in the literature, the frequencies of these modes fairly agree with computed and IR values. [31] The formation of such species as reaction intermediates strengthens the proposed reaction mechanism based on the successive addition of H atoms and COH radicals.…”

Electrode Reactions of Elemental (White) Phosphorus and Phosphane PH3

“…[64] To realize the in situ preparation of this new and intriguing compound, a single electrochemical cell supplied with a lead cathode and a sacrificial zinc anode was used. However, surprisingly, we were able to generate a new inorganic phosphorus compound: phosphane oxide H 3 PO.…”

“…In the first step, the electrochemical generation of PH 3 from white phosphorus on the lead cathode takes place, and in the second step, mild oxidation of PH 3 to H 3 PO occurs at the surface of the zinc anode. [64] To elucidate the role of the Zn anode in the process of H 3 PO electrochemical synthesis, the same experiments have been performed using a GC anode in the presence and in the absence of specially added Zn 2+ ions (from ZnCl 2 ). [64] Scheme 20.…”
