Abstract
1 H/19F NMR two-dimensional exchange spectroscopy (EXSY) reveals that the 1,4-metallotropic shifts in bidentate chelate complexes of a substituted 2,2′ : 6′,2″-terpyridine ligand occur by an associative mechanism involving five-coordinate intermediates for PdII and PtII complexes, and seven-coordinate intermediates for PtIV and, by analogy, ReI complexes.Keywords
