烯烃中双键的位置可以很容易地通过其甲氧基汞化产物的硼氢化钠还原和质谱分析来确定。甲氧基衍生物在质谱仪中的裂解会导致甲氧基的两侧发生裂解，从而产生强烈的碎片离子，这是每个异构体的特征。这一简单方便的微量分析技术被应用于几种合成标准和昆虫衍生的烯烃，包括从蜜蜂的角质层脂肪中提取的烯烃。
The positions of double bonds in olefins can be readily determined by a sodium borohydride reduction of their methoxymercuration products followed by mass spectrometry. Fragmentation of the methoxy derivative in the mass spectrometer results in cleavage on either side of the methoxy group to give intense fragment ions which are characteristic of each isomer. This simple and convenient microanalytical technique was applied to several synthetic standards and insect derived olefins, including the alkenes from the cuticular lipids of the honeybeeApis mellifera L.
