The preparation of a macrocyclic diphosphine ligand 5 incorporating a binaphthyl unit and its NiII and PdII complexes, 6 and 7, is described. A complete assignment of 1H,- 13C-, and 31P-NMR data on the basis of 2D NMR spectroscopy (1H, 1H-, 13C, 1H-, 31P, 1H-, 31P, 13C-COSY) was possible for 5, and also – in part – for 6 and 7.
