H/D exchanges of arylmethyl amines and nitrogenheterocycles were conveniently achieved with KOt-Bu/DMSO-d6. The method is also applicable for phenyl benzyl ethers, diarylmethanes, and alkyl arenes. These H/D exchange reactions are suggested to proceed via a free radical pathway.
芳基甲胺和氮杂环的H / D交换可通过KO t -Bu / DMSO- d 6方便地实现。该方法也适用于苯基苄基醚,二芳基甲烷和烷基芳烃。这些H / D交换反应被建议通过自由基途径进行。

AbstractLow‐valent titanium readily prepared in situ from TiCl4 and Mg powder in THF is found to be an active agent for the reduction of amides which were previously considered to be inert towards low‐valent titanium. The reaction proceeds under very mild conditions, and is applicable to all types of amides, primary, secondary and tertiary, to produce the corresponding amines in good to excellent yields. This new finding provides a practical, convenient and general method for the important transformation of amides to amines. A plausible reaction mechanism is proposed.magnified image
