Raman spectrum of gaseous phosphaethyne (HCP) - Kalasinsky

WebJul 1, 1983 · The molecule phosphaethyne, HCP, was first prepared by Gier (14) in 1961. It was investigated by microwave (15, 16), electronic (17), infrared (14, 17-19), NMR (20), and photoelectron (21) spectroscopy. WebPhosphaethynes bearing a 2,6-di-tert-butyl-4- (dimethylamino)phenyl, 2,6-di-tert-butyl-4-methoxyphenyl, or 2,6-di-tert-butylphenyl group were prepared. A 31 P NMR spectroscopic investigation of the chemical shifts indicated that electron-donating groups at the para position cause shifts to a higher field.
