Abstract
The F-19 NMR investigation of exchange equilibria in the systems Ar3Sn SC6H4F-4 + Ph3SnCl has shown that the chemical hardness of Ar3Sn+ cati ons decreases with increase in electron-accepting ability of aryl liga nds. It has been found that the influence of aryl ligands on the chemi cal hardness of Ar3Sn+ cations is well described by sigma degrees cons tants of substituted phenyl groups. The correlation of log K-e with th e electronegativities of Ar3Sn groups strongly suggests the contributi on of electronegativity factors. (C) 1997 Elsevier Science S.A.
