Abstract Interaction of monoorganotin trichlorides (RSnCl 3, R= Ph, Vin, All, Bn and c-Pr) with O-TMS-amides of 2-hydroxycarboxylic acids afforded a number of mononuclear and binuclear organotin complexes (2a–j). These organotin complexes disproportionate into diorganostannanes and inorganic coordination compounds containing two O, O-chelated ligands (3a–c). All the complexes were characterized by multinuclear NMR spectroscopy ...
