（η（5）-Ph 5C 5）Ru（CO）（2）（Ot-Bu）与5-己烯-2-醇的反应产生具有与钌配位的双键的烷氧基羰基络合物的两种非对映异构体。通过H-1和C-13 NMR光谱和原位FT-IR测量对配合物进行了表征。C-13 NMR羰基。络合物的峰以1：1：2的比例出现在203.48、203.55和204.0ppm处。在1982（CO）和1644（酰基）cm（-1）处检测到CO和酰基的IR峰。
Reaction of (eta(5)-Ph5C5)Ru(CO)(2)(Ot-Bu) with 5-hexen-2-ol produces two diastereomers of an alkoxycarbonyl complex having the double bond coordinated to ruthenium. The complexes were characterized by H-1 and C-13 NMR spectroscopy and in situ FT-IR measurements. The C-13 NMR carbonyl. peaks of the complexes appear at 203.48, 203.55, and 204.0 ppm in a ratio of 1:1:2. IR peaks for CO and acyl were detected at 1982 (CO) and 1644 (acyl) cm(-1).
