摘要
Long range (5)J and (6)J (H-1-F-19) spin-spin coupling constants for a set of nine biarylic fluorinated derivatives were determined by H-1 NMR experiments. The quantitation of these long-range (5)J and (6)J (H-1-F-19) coupling can be found through the measure of the residual coupling-signals obtained after the selective decoupling process. The information obtained for the NMR spectra was confirmed through computational studies. (C) 2018 Elsevier B.V. All rights reserved.
