A highly effective and operationally practical method for the regioselectivedeuteration of N-alkyl-substituted anilines employing Ru3(CO)12 (⩽1 mol %) as catalyst and D2O as deuterium source was described. A variety of N-alkyl-substituted anilines were efficiently deuterated (up to 98%) at the ortho and/or para position with respect to the nitrogen at neutral conditions. Under the present conditions

Deuterium labeled compounds find widespread application in life science. Herein, the deuteration of electron-rich (hetero)aromaticcompounds employing B(C6F5)3 as the catalyst and D2O as the deuterium source is reported. This protocol is highly efficient, simply manipulated, and successfully applied in the deuteration of 23 substrates including natural neurotransmitter-like melatonin. It is assumed
氘标记的化合物在生命科学中得到广泛应用。在此,报道了以B(C 6 F 5)3为催化剂,D 2 O为氘源的富电子(杂)芳族化合物的氘化。该协议高效,简单易操作,并成功应用于包括自然神经递质类褪黑激素在内的23种底物的氘化。假定O–D键的弱化最终导致亲电性D +的形成。
