Isotope labeling is an important method to evaluate drugs and compounds for agricultural use. Therefore, a fast and convenient method to selectively exchange hydrogen against non-radioactive deuterium or radioactive tritium in the final product is desirable. PHIP-NMR investigations of the influence of CO on the selective exchange of the geminal protons in styrene show that CO increases the efficiency
同位素标记是评估农业用药物和化合物的重要方法。因此,需要一种快速方便的方法来选择性地将氢与最终产品中的非放射性氘或放射性氚进行交换。CO 对苯乙烯中孪生质子选择性交换影响的 PHIP-NMR 研究表明,CO 非线性地提高了选择性交换的效率并抑制了苯乙烯氢化成乙苯。版权所有 © 2000 John Wiley & Sons, Ltd.
