STUDIES ON THE PROPERTIES OF SCHIFF BASE TYPE ARYLMERCURY COMPOUNDS.II ^(199)Hg NMR SPECTRA OF MERCURATED DERIVATIVES OF SUBSTITUTED BENZYLIDENEANILINES

摘要

199Hg NHR spectra of 18 Schiff base type arylmercury compounds have beenstudied.It was further confirmed that in the molecule of XC₆H₄CH=NC₆H₃-2-HgC1-4-CH₃there exists an intramolecular N→Hg coordination via a four-membered ring.For theseries of XC₆H₄CH=NC₆H₃-2-HgCl-4-CH₃（X is a para-or mera-substituent）,there is agood linear correlation between δ199Hg and Hammett’s o constants.The influence ofsubstituents of C-pheny1 ring on the δ 199Hg can be explained in terms of theintramolecular N→Hg coordination.
