“…Fluorine-19 magnetic resonance investigations have been carried out on xenon oxytetrafluoride (1866), fluorinated phenyl-terf-butyl nitroxide radicals (1867), Group II difluorides (1868), boron trifluoride complexes with some aliphatic and aromatic ethers (1869), boron trifluoride complexes with acetylacetone derivatives (1870), other boron trifluoride adducts (1871), fluoroborate species (1872), and boron trihalide complexes with pyrazine derivatives (1873). Spectra have been utilized in reactions of methylchlorodisilanes (1874), dehydrofluorination and cleavage of silicon nitrogen bonds in boron trifluoridesilylamine systems (1875), intramolecular fluorine exchange in diphenyltrifluorophosphorane (1876), diamagnetic shielding of fluorine-19 nuclei in tetrahedral and octahedral fluorides of nontransition elements (1877), and temperature dependencies of fluorine-19 NMR spectral parameters in tetrafluoroborate solutions (1878).…”
