✦ Synopsis

The complete assignment of 19 F, 1 H and 13 C NMR spectra for a monosubstituted octafluoro[2.2]paracyclophane derivative is described for the first time. The unambiguous assignments were achieved through the combination of 19 F-1 H HOESY, 1 H COSY and 19 F COSY techniques and then further confirmed employing a complementary approach using a Karplus-dependent 3 J CF interaction. Interesting aspects of the coupling patterns for various J HH , J HF , J CF and J FF interactions are also discussed. Copyright

## Abstract Complete assignment of the ^1^H and ^19^F chemical shifts in 4‐fluoro‐AF4 (1) were based on the nOes seen in its ^19^F‐^1^H HOESY spectrum. This allowed for identification of features which can further be applied to the assignment of the regiochemistry of substituted perfluoroparacyclop
