Synthesis and structure of new Schiff base derivatives obtained from 2-(formylphenyl)mercury bromide

Reactions of (2-formylphenyl)mercury(II) bromide 10 with primary amines give mono-, bis- and tris- Schiff base derivatives (11–18). Structures of the synthesized compounds show the presence of five-membered intramolecular Hg⋯N interaction. Luminescence studies of the compounds have been performed. Attempts to use the synthesized compounds for binding neutral donor molecules or fluoride ions were unsuccessful.

A series of Schiff base derivatives of 2-(formylphenyl)mercury(II) bromides have been synthesized and studied. The isolation of enantiomerically pure arylmercury bromide due to the presence of an intramolecular coordination is reported.Figure optionsDownload as PowerPoint slideHighlights
► A series of organomercury Schiff base derivatives are synthesized.
► These derivatives exhibit intramiolecular secondary Hg⋯N interactions.
► Schiff base derivative of aniline is chiral without a stereocentre.
► Organomercury derivative of phenylenediamine exhibits weak Hg⋯Hg interaction.
