Ortho-tellurated derivatives of some arylamines and imines

摘要

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-methylamino-methyl)ferrocene, tricarbonyl (N,N-dimethylbenzenemethanamine) chromium and 2-(3-thienyl)-pyridine. In addition novelchiral hybrid Schiff base ligands have been prepared by the condensation reaction of bis(o-formylphenyl) telluride and o-butyltellurobenzaldehyde with (R)-( + )-l-phenethylamine and (R, 2S)-(-)-norephedrine.
