Substituent Effects in 13C- N. M. R. Spectra of Diastereomeric Chalcone Dihalogenides. V. Synthesis, Stereochemistry and Spectroscopy of Chalcone FluorohydrinesChalcone fluorohydrins 1 and diastereomeric pairs of chalcone chlorohydrins 2 as standards are investigated in the i.r., 1H, 19F, and 13C n m. r. spectroscopy field. The substituent dependence of the spectral parameters is discussed.The assignment of conformation and configuration on the basis of vicinal 1H—1H, 1H—19F, and 1H—13C coupling constants is determined.
