Synthesis and Molecular Structure Study of New Organotellurium and Organomercury Compounds Based on 4-Bromonaphthalen-1-amine

Abstract

The new organic derivatives of mercury and tellurium have been prepared by a reaction of 4-bromonaphthalen-1-amine with Hg(CH3COO)2 and further with TeBr4. Reaction of (1-amino-4-bromonaphthalen-2-yl)mercury(II) chloride with benzaldehyde then TeBr4 has produced the new aryaltellurium(IV) tribromide containing the azomethine moiety. Reaction of 4-bromo-2-(tribromo-λ4-tellanyl)naphthalen-1-amine with 4-hydroxyphenyl mercury(II) chloride gives asymmetrical diaryaltellurium(IV) dibromide. Reduction of aryaltellurium tribromide and diaryaltellurium dibromide by hydrazine hydrate leads to the corresponding diaryalditelluride and diaryaltullride. Structures of the synthesized compounds have been elucidated from FT-IR, 1H, and 13C NMR spectra. The molecular structures and energies for the compounds were also calculated according to the DFT concept.
