Abstract

119Sn NMR data are reported for organotin compounds containing potentially C,N‐chelating ligands capable of forming five‐ or six‐membered chelate rings. The 119Sn chemical shifts of divalent organotin compounds containing such a ligand are found at relatively high frequency. Intramolecular coordination in tetraorganotin compounds has little influence on their 119Sn chemical shifts. However, additional coordination in tri‐ and di‐organotin halides causes a large shift to lower frequency of about 100 ppm. Finally, for organotin compounds which exist as a diastereoisomeric mixture in solution, two well resolved 119Sn resonances are observed.
