Abstract

Salts IV and V are white hygroscopic crystals. The NMR spectra of IV contain characteristic signals of the PC 1 H2C 2 H (C 5= O) C 3 H2C 4= O and PC 6 H2NC 7 H3 fragments. Their parameters are listed below. The 1 H NMR signals of these fragments partially or completely overlap. Phosphinates III contain asymmetric carbon and phosphorus atoms, and, according to NMR data, these compounds exist as mixtures of two stereoisomers. The spectral data ...
