Triazabicyclodecene:  An Effective Isotope Exchange Catalyst in CDCl3

Posted on 2007-06-22 - 00:00
We describe the first effective H/D exchange reaction with acidic substrates in CDCl3 at room temperature. The particularly mild reaction conditions involved (solvent, base, and temperature) allow the chemoselective deuteration of ketones over esters. An NMR study was conducted with the aim of rationalizing the results obtained in the presence of TBD as catalyst.
