摘要：

Fine tuning of the nonbonding FF distances, by bridge length variation and suitable substituents, in a series of difluorometa‐ (1) and ‐paracyclophanes led to a new quantitative description of distance‐dependent 19F, 19F through‐space spin–spin coupling. This will be useful for structural studies of di‐ and oligofluorinated compounds in solution. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
