过渡金属催化烯丙醇的选择性脱氢氧化以得到相应的α,β-不饱和羰基化合物在最近广受关注,但是很多方法需要用到化学计量的氧化剂,这会带来大量的废弃副产物,原子经济性不足.本工作开发了一种简单易得的[RuCl2(p-cymene)]2催化系统,可用于高效地催化烯丙醇选择性脱氢合成α,β-不饱和羰基化合物,而无需使用额外的氧化剂或H2受体.“,”Transition metal-catalyzed allyllic alcohol selective dehydrogenation to generate the corresponding a,β-unsaturated carbonyl compound has attached great attention.However,most of these methods require stoichiometric quantities of oxidants,which will bring a lot of by-products and lack of atomic economy.Herein,a simple[RuCl2(p-cymene)]2 catalyzed system to efficiently catalyze the selective dehydrogenation of allyl alcohol to form α,β-unsaturated carbonyls without the use of additional oxidants or H2 acceptors has been developed.
