Abstract
AbstractData derived from the carbon‐13 NMR spectra of 37 organic polychloro compounds allow one to identify readily the CHCl2, CCl2 and CH2Cl groups, the 13C signals of which are registered in the shift ranges of 67 to 78 (80), 85 to 96 and 38 to 55 (59) ppm (from TMS), respectively, and have the distinctive one bond spin‐spin coupling constants 1J(CH) 170 to 184 Hz (for the CHCl2 groups) and 147 to 158 Hz (for the CH2Cl groups). The CCl2CH2CH2Cl fragment features characteristic diamagnetic shieldings of the CCl2 and CH2Cl that may be related to increased electron density on both of these groups.
