and diastereoisomers [Os(CO)(µ-H)µ:η:η:η-κ(-BuP(CHCHCH)(CCHCH)}] (). and which were characterized by X-ray analysis. To the best of our knowledge, is the first characterized structure involving isomerization of the double bond of the allylic substituent at room temperature in the case of metallic clusters. X-ray coordinates were used to study the possible reaction mechanisms through computational calculations
丁基二
烯丙基膦与 [Os(CO)(CHCN)] 反应得到化合物 [Os(CO)κ()-BuP(CHCHCH2)}] , [Os(CO)κ()-BuP(CHCHCH)}] 、 [Os(CO)κ()-BuP(CHCHCH)}] 、非对映异构体 [Os(CO)μ:η-κ()-BuP(CHCHCH)}] () 和 [Os(CO)μ: η-κ(-BuP(CHCHCH))(κ-BuP(CHCHCH)}] (). 热解或得到复合物 [Os(CO)(μ-H)μ:η:η:η-κ-P (CHCHCH)(CCHCH)}] 和非对映异构体 [Os(CO)(μ-H)μ:η:η:η-κ(-BuP(CHCHCH)(CCHCH)}] ()。据我们所知,这是第一个在
金属簇的情况下涉及烯丙基取代基双键异构化的特征结构,用于通过计算研究可能的反应机制。在 MN15L/def2svp 理论
水平上进行计算,实验结果与计算结果之间取得了良好的一致性。
