(CM) reactions of methyl oleate (MO) with cis-4-octene (OC), cis-stilbene (CS) using RuCl2(PCy3)(IMesH2)(CHPh) [IMesH2 = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene; Cy = cyclohexyl] afforded CM products with high MO conversion and high selectivity under high molar (OC/MO, CS/MO) ratios; CM with cis-1,4-diacetoxy-2-butene also afforded metathesis products with high MO conversion under certain conditions
交叉复分解(CM)(MO)与油酸甲酯的反应顺-4-辛烯(OC),顺式-芪(CS)使用的RuCl 2(PCY 3)(的iMesh 2)(CHPh配合)的iMesh 2 = 1,3-双(2,4,6-三甲基苯基)咪唑啉-2-亚烷基; [Cy =环己基]在高摩尔(OC / MO,CS / MO)比下提供了具有高MO转化率和高选择性的CM产物。在某些条件下,带有顺式-1,4-二乙酰氧基-2-丁烯的CM还提供了具有高MO转化率的复分解产物。具有烯丙基三甲基硅烷的有效CM具有较高的活性,而具有缩水甘油醚,β-pine烯和Vanillylidenacetacetone的CM具有较低的MO转化率。
