states of palladium is described, which mediates the isomerization of alkynyl epoxides to furans. In a process termed “dual oxidation state tandem catalysis”, a multistep isomerization pathway is delineated in which the different metal oxidation states and ligands play independent mechanistic roles, but which, in combination, enable the use of milder reaction conditions and lower catalyst loadings than
描述了由钯的不同氧化态组成的两催化剂体系,其介导炔基环氧化物异构化成呋喃。在一个称为“双氧化态串联催化”的过程中,描绘了一个多步异构化途径,其中不同的金属氧化态和配体起着独立的机械作用,但与之相比,它们可以使使用更温和的反应条件并降低催化剂的负载量。孤立的单个催化剂。在本文中,同双金属催化转化的这一罕见实例为呋喃合成提供了温和,可扩展和原子高效的途径。
