Disclosed is a method for the transition metal-mediated oxidation of C—H bonds to form C—O or C—S bonds. The methods are useful for the formation of ethers (R—OR′) from alcohols, R′OH, and sp

-hybridized C—H bonds in substrates, R—H. Aryl or heteroaryl acetates may also be used for C—H to C-OAr bond formation. The methods are also useful in the preparation of C—S bonds from acetyl-protected thiols, MeC(O)SR, and disulfides, RSSR. Advantageously, the methods minimize reaction steps, the handling of oxidized intermediates, and environmental impact.
本发明公开了一种过渡金属介导的氧化C-H键形成C-O或C-S键的方法。该方法可用于从醇,R'OH和底物中的sp3杂化C-H键形成醚(R-OR')。芳基或杂环基乙酸酯也可用于C-H到C-OAr键的形成。该方法还可用于从乙酰保护的硫醇,MeC(O)SR和二硫化物,RSSR中制备C-S键。该方法具有反应步骤少,处理氧化中间体少,对环境的影响小的优点。
