Dependence of presence of defect in g-Al2O3 toplayer on structure of support 底膜结构对g-Al2O3顶层缺陷存在的决定作用
Resumo:
Lewis acid assisted ring-closing olefin metathesis (RCM) of chiral diallylamines, using the second generation RCM ruthenium-based catalyst, leads to enantiopure pyrrolidine derivatives in 79-93% yields under very mild conditions. The scope of the olefin metathesis has been expanded.
