TL;DR: In this paper, the synthesis of a new carbacylamidophosphate compound, [chloro(difluoro)acetyl]phosphoramidic acid dichloride (ClF 2 CC(O)NHP (O)Cl 2 ), is reported along with its FTIR, Raman and mass spectra.
Journal ArticleDOI
Trifluoroacetylsulfenyl Trifluoroacetate, CF3C(O)−S−O−C(O)CF3, a Novel Compound with a Symmetrically Substituted S−O Bond: Synthesis, Spectroscopic Characterization, and Quantum Chemical Calculations
TL;DR: Comparison with theoretical results indicates that the structural properties of sulfenyl compounds are more similar to those of disulfides than toThose of peroxides.
Journal ArticleDOI
Preparation and properties of trifluorothioacetic acid-S-(trifluoromethyl)ester, CF3C(O)SCF3.
TL;DR: GED and vibrational spectroscopy result in the presence of a single conformer with C1 symmetry and synperiplanar orientation of the S-CF3 bond relative to the CO bond, in agreement with quantum chemical calculations which predict the anti conformer to be higher in energy by about 4 kcal/mol.
Journal ArticleDOI
Keto–enol tautomerism in β-ketoesters: CH3C(O)CHXC(O)OY (X = H, Cl; Y = CH3, C2H5). Vibrational analyses, NMR spectra and quantum chemical calculations
M.M. Schiavoni,H.E. Di Loreto,Angelika Hermann,Hans Georg Mack,Sonia E. Ulic,Sonia E. Ulic,C.O. Della Védova +6 more
TL;DR: In this paper, the tautomeric equilibria of β-ketoesters were studied by NMR spectroscopy and, in the case of I and II, by quantum chemical calculations (ab initio and density functional methods).
