Conclusions
-
1.
The bridge group N(SO2C6H5) in compounds C6H5HgN(SO2C6H5)Ar is less capable of conducting the influence of the effect of conjugation of substituents in the aryl ring on the chemical shifts of199Hg in comparison with the -CH2- and -OC(O)- groups in the corresponding benzyl derivatives and phenylmercury benzoates.
-
2.
Intramolecular coordinatation of o substituents in the N-aryl ring with the mercury atom leads to a strong unshielding of the199Hg nuclei.
-
3.
The chemical shifts of the199Hg are sensitive to the steric effects of the alkyl groups at the N atoms in the compounds C6H5HgN(SO2C6H5)Alk.
