Mechanistic and spectroscopic investigations of reactive C3H2 hydrocarbons necessitated the preparation of diazopropyne isotopomers bearing mono‐13C substitution at each of the three unique positions. The diazo compounds and their tosylhydrazone precursors were prepared from the mono‐13C isotopomers of propynal (in the form of either the aldehyde or the diethyl acetal). The introduction of 13C‐labeling
对反应性C 3 H 2烃的力学和光谱研究使得必须制备在三个独特位置均带有单13 C取代基的重氮丙炔异位异构体。重氮化合物及其甲苯磺酰zone前体是由丙炔的单13 C异构体(以醛或二乙缩醛的形式)制得的。在丙炔的任一炔烃位置引入13 C标记,利用Corey - Fuchs程序进行链同源。
