WebThe Raman spectrum of gaseous phosphaethyne (HCP) has been recorded, and the C H and C P stretching vibrations (ν1and ν3) have been observed at 3218 and 1277 cm−1, respectively. These frequencies compare very favorably with those previously determined from IR and UV-visible spectra. WebFeb 4, 2010 · Formation of phosphaethyne trimers by reaction of phosphaethyne and 1,4-diphosphatriafulvene has been determined. This suggests that the thermodynamically controlled product is the 1,3,5-triphosphinine, while 1,3,6-triphosphafulvene is the kinetically favored product. For the latter a biradical reaction pathway also exists.
