Vibrational frequencies and structural determination of phosphorous tricyanide

Organometallic Lewis Acids, Part LIX[1] Pentacarbonylrhenium Complexes with Phosphorus Tricyanide and Di­cyanophosphide

“…The ν(CN) absorption of 1 (2222 cm –1 in CH 3 CN) is shifted to higher wavenumbers in comparison to “free” P(CN) 3 (2204 cm –1 ) 8,9. This observation provides strong evidence that the Re(CO) 5 cation is coordinated to the cyano groups of P(CN) 3 .…”

Quantum Chemical Simulation of Phenol-Formaldehyde Resin Carbonization in the Presence of Phosphoric Acid: Computational Evidence of Michaelis–Arbuzov-Type Reaction

“…On the basis of the QC-derived data, one can notice that the C–P bonds in the models described above are different from those in phosphine-derived ones (triethylphosphine, phosphorus tricyanide, etc. ), which are used as a reference. , In the latter ones the C–P bonds are less polar (charge separation ∼0.5) than in phosphonates (charge separation ∼1.5), which should affect the force constant of the bond and thus change the position of ν(C–P) band.…”

“…Unfortunately, phosphoric ester and phosphonate groups on carbon are hard to distinguish by XPS analysis. , In the latter concern, there are a number of papers stating an absence of C–P bonds based on IR spectra. , The main argument is that the ν(C–P) band in organophosphate compounds is observed at ∼700–620 cm –1 , , whereas no such adsorption feature can be found in the IR spectra of the carbons obtained from H 3 PO 4 -treated PhF resins. However, in this approach several crucial points are missed, mainly due to the lack of data on the manner of phosphonate groups bonding to the carbon moiety.…”
