Tf₂O-Mediated P(O)–N Bond Formation of Either P(O)–OH or P(O)–H Reagents with Multitype Amines

The Journal of Organic Chemistry
We have developed a Tf2O-mediated approach for the direct amination of either P(O)-OH or P(O)-H reagents with a variety of aliphatic or aromatic amines. Without the requirement of precious metals and toxic reagents, this protocol provides an alternative route to various phosphinamides and phosphoramides.

Ultrasonic tests for phase separation in the vitreous systems Co-P-O and H-P-O

Journal of Materials Science, 1985
Original data on ultrasonically determined elastic moduli of the vitreous systems Co-P-O and H-P-O have been used as a phase separation test for these glasses. For the Co-P-O system whose compositions ranged from 5 to 60 mol% CoO, no evidence for phase separation in any part of the composition range 0 to 42 mol% CoO could be found. The possibility of a

Double phosphates NaMn???(P???O??????)(P???O???)??? and KMn???(P???O??????)(P???O???)??? - advanced functional materials

2019
Complex phosphates containing two different ions have been identified in the fluxes of M???O-P???O???-Mn???O??? systems (where M - Na, K) for the first time. Optimum conditions for the growing of single crystals of NaMn???(P???O??????)(P???O???)??? and KMn???(P???O??????)(P???O???)??? compounds have been selected.

Infrarotspektroskopische Untersuchungen an Fluorphosphorverbindungen. I. POP‐ und PO‐Streckschwingungen in Fluor‐diphosphorsäurederivaten

Zeitschrift für anorganische und allgemeine Chemie, 1965
AbstractDie Infrarotspektren von Fluor‐diphosphorsäurederivaten wurden im Bereich von 400–3100 cm−1 aufgenommen. Es wird über Charakteristika der POP‐ und der PO‐stretching‐Frequenzen dieser Verbindungen berichtet. Die γas(POP)‐Schwingung zeigt höhere Frequenzen, verglichen mit analogen fluorfreien Diphosphaten.
