Rapid Proton

Aromatics undergo rapid proton-deuterium or -tritium exchange in aqueous solutions containing Raney nickel alloy. The specificity of exchange in benzoic acid, anthranilic acid, pyridine and aniline is investigated by degradation and mass and N.M.R. spectrometry. Positions meta and para to carboxylate are most readily exchanged.

The Relationship

Herein we examine the relationship between reaction rate and reaction selectivity in iridium-catalysed hydrogen isotope exchange (HIE) reactions directed by Lewis basic functional groups. We have recently develped a directing...
