Influence of substituents on the chemical shift of fluorine in certain fluorosubstituted arylphenylmercury compounds and N-arylmercury derivatives of benzenesulfonanilide

A comparative investigation is made by the /sup 19/F-/sup 1/H NMR method of a series of mono- and binuclear bridge systems containing 3- and 2-fluorophenyl indicator groups ArHgC/sub 6/H/sub 4/F-3 (2) and ArHgN (SO/sub 2/Ph) C/sub 6/H/sub 4/F-(2). It was established that in both types of systems the chemical shift (CS) of fluorine in the 3 position, in contrast to the CS of fluorine in the 2 position, is determined chiefly by the electronic influence of the substituents.
