Abstract
The exchange equilibria: Ph3Sn-X + Ph3Pb-SC6H4F-4 reversible Ph3Pb-X Ph3Sn-SC6H4F-4 (X=OH, Cl, Br, I) have been studied in CHCl3 by F-19 N MR. Good correlations of equilibrium constant logarithm with the Pears on parameters of absolute and chemical hardness have been found. On th e basis of these relationships and general consideration of exchange e quilibria it has been shown that the study of exchange reactions invol ving hard and soft HX-acids and their L(n)M-derivatives permits study of quantitative regularities in ligand influence on the hardness of or ganometallic cations.
