Abstract
A number of organomercury, -tin and -lead derivatives of m- and p-fluoro-substituted phenols and thiophenols of the type R n MOAr and R n MSAr have been prepared. The 19F chemical shifts relative to fluorobenzene have been measured in various solvents for all these compounds. On the basis of the data obtained, the electronic features of the substituents R n MO and R n MS have been studied and compared with those of OH, CH 3O, SH and CH 3S groups. The influence of various factors on the electronic effect of the organometallic substituent and on its solvent susceptibility is discussed. The coordinating abilities of the substituents (C 2H 5) 3SnO and (C 2H 5) 3-SnS in solution have been compared with those of the OH and SH groups.
