Abstract

A PMR study of solvent effects on some p‐substituted phenyltin chlorides (substituents = CH~3~, (CH~3~)~3~C, CH~3~O) is reported. Co‐ordination of solvent molecules to the tin atom leads to an unusual low field shift of the o‐ring protons. The results for p‐tolytin trichloride have been compared with those for p‐tolylsilyl trichloride and discussed. In o‐, m‐ and p‐tolyltin trichlorides long range spin‐spin couplings between the ring methyl protons and the tin atom have been observed. The order of magnitude is o‐ > p‐ > m‐methyl protons.

Proton NMR data for a number of l-.IZ-4-Y-3,5-dimethylbenzenc?s and l-X-2-Y-4-Z-3,5-dimethylbenzenc?s are presented. The proton chemical shifts of the methyl groups at positions 3 and 5 are mainly affected by the ring current effect of the snbstituents. Thii conclusion was strongly supported by the
