Abstract
One- and two-dimensional fluorine NMR spectra of straight-chain chlorofluoroalkanes having 7-10 carbons were obtained and interpreted. Spectral assignments were based primarily on indirect spin-spin correlations. A scale of chlorine substituent effects was developed. The effects of asymmetric CFCl centers on chemical-shift differences in nearby CF2 groups were analyzed in terms of molecular conformational effects. Spin-spin coupling patterns of CF3 groups were elucidated.
