A palladium on carbon (Pd/C)‐catalyzed synthetic method for the preparation of benzil derivatives from 1,2‐diarylalkynes has been established using dimethyl sulfoxide (DMSO) and molecular oxygen as dual oxidants. Regardless of the electrical nature of the functional groups on the aromatic rings, 1,2‐diarylalkynes were oxidized to the corresponding benzil derivatives in high to excellent yields. Furthermore
建立了一种以钯碳(Pd / C)催化的合成方法,使用二甲基亚砜(DMSO)和分子氧作为双氧化剂,从1,2-二芳基炔烃制备苯甲醚衍生物。无论芳环上官能团的电性质如何,1,2-二芳基炔烃都可以高产率或高产率被氧化成相应的苯甲腈衍生物。此外,在大气条件下,干式和湿式Pd / C均可有效地催化氧化。
