sulfur atom results on a difference in the activity of this tandem reaction. Experimental observations demonstrate that the isomerization process is the rate‐determining step of this catalytic transformation. This process would be of value to the chemical industry because mixtures of internal aliphatic olefins are substantially cheaper and more readily available than the pure terminal isomers.

硫原子上取代基大小的不同导致了该串联反应活性的差异。实验观察表明,异构化过程是该催化转化的决定速率的步骤。该方法对于
化学工业将是有价值的,因为内部脂族烯烃的混合物比纯末端异构体便宜得多并且更容易获得。
