CH⋅⋅⋅FC interactions and their nature, importance, and applicability is a topical yet contentious issue. As described by M. C. W. Chan, K.‐H. Sze et al. in their Full Paper on page 565 ff. , a series of Group 4 organometallic complexes supported by (σ‐aryl)‐chelating ligands, with a CF 3 or F substituent in the vicinity of the metal, has been designed and characterized by multinuclear NMR experiments, which for the first time verify that the observed 1 H– 19 F coupling contains a scalar component, and therefore occurs with chemical connectivity across intramolecular CH⋅⋅⋅FC contacts for Ti derivatives.
