摘　　要：烯烃的选择性氧化断裂反应是合成功能羰基化合物最高效的途径之一。以简单烯烃为原料,365 nm紫外光为光源,六羰基钨为催化剂,以氧气为单一氧化剂合成制备了结构多样的醛、酮类衍生物。通过考察催化剂、溶剂、氧化剂以及光源等因素,筛选得到最佳反应条件。该反应方法具有操作简单、条件温和、官能团容忍度高、底物普适性广及可克级规模制备等优点,展现了该反应在精细化工、材料等领域的应用潜力。The selective oxidative cleavage reaction of alkenes is defined as one of the most effective routes for the construction of carbonyl compounds.In this work,a wide range of aldehyde and ketone derivatives were synthesized by utilizing simple alkenes as starting materials,365 nm UV light as light source,tungsten hexacarbonyl as catalyst and the molecule dioxygen as the sole oxidant.The optimal reaction conditions were determined via the investigation of catalysts,solvent,oxidants and light source.Moreover,this protocol featured the advantages of simple operations,mild reaction conditions,good functional group tolerance,broad substrate scope and gram scale synthesis,which demonstrated the potential of this transformation in the field of fine chemicals and material science.
