Preparation of deuterium-labelled perhexiline from an unsaturated analogue was performed via reduction with deuterium gas and PtO2 in acetic acid. Low incorporation was observed when using acetic acid as solvent (most abundant mass peak was M), but when changing the solvent to deuterium-labelled acetic acid, e.g. acetic acid-OD or acetic acid-d4, a higher incorporation was observed (most abundant mass peak was M). Using hydrogen gas instead of deuterium gas with deuterium-labelled acetic acid, high levels of deuterium incorporation were observed (most abundant mass peak was M). An attempt to reduce a precursor with a fully deuterated pyridine to obtain perhexiline with a higher content of deuterium failed. Copyright © 2009 John Wiley & Sons, Ltd.
通过在乙酸中使用氘气和二氧化铂进行还原,从不饱和类似物中制备出了氘标记的过苯胺。当使用乙酸作为溶剂时,观察到的掺入量较低(最丰富的质量峰为 M),但当将溶剂改为氘标记的乙酸时,如乙酸-OD 或乙酸-d4,观察到的掺入量较高(最丰富的质量峰为 M)。用氢气代替氘气与氘标记的醋酸混合,观察到了高水平的氘掺入(最丰富的质量峰为 M)。试图用完全氚化的吡啶还原前体以获得氘含量更高的过六次甲基苯胺的实验失败了。Copyright © 2009 John Wiley & Sons, Ltd. All Rights Reserved.
