平面手性二烯烃有机氮环1与3进行了立体定向和基团选择性烯烃交换得到4，其分子结构通过核磁共振和x射线衍射进行了表征。4中键合的(E)-烯烃基团足够坚固，使得未接触的(Z)-烯烃进行环氧化和氢化反应，得到相应的PtCl2（η - 2-烯烃）配合物，用PPh3处理后，其烯烃部分顺利释放，否则难以合成。
The planar chiral diolefinic organonitrogen cycles 1 underwent stereospecific and group-selective olefin exchange with 3 to give 4, whose molecular structure was characterized on the basis of NMR and X-ray diffraction. The bonded (E)-olefin moieties in 4 were robust enough to allow untouched (Z)-olefin to undergo epoxidation and hydrogenation to give the corresponding PtCl2(η2-olefin) complexes, whose treatment with PPh3 smoothly liberated their olefinic parts, which would be otherwise difficult to synthesize.
