Ortho-tellurated derivatives of some arylamines and imines

Abstract

A range of novel bi-, tri- and multidentate organotellurium ligands containing Te and N donor atoms and their derivatives have been synthesised. The synthetic strategy involves telluration of orthochelating, monoanionic substrates derived from the following arylamines: N, N-dimethylbenzylamine, (S)-(-)-N,N-dimethyl-1-phenethylamine, N,N-dimethylnaphthylamine, (N,N-di-methylaminomethyl)ferrocene, tricarbonyl (N,N-dimethylbenzenemethanamine) chromium and 2-(3-thienyl)-pyridine. In addition novel chiral hybrid Schiff base ligands have been prepared by the condensation reaction of bis(o-formylphenyl) telluride and o-butyltellurobenzaldehyde with (R)-(+)-1-phenethylamine and (1R, 2S)-(-)norephedrine.
