Development of a mild (35 °C, no Brønsted acids) tandem Wacker oxidation-dehydrogenation of terminal olefins was accomplished using palladium(II) and hypervalentiodine co-catalysis. The reaction affords linear aryl and alkyl α,β-unsaturated ketones directly from readily available terminal olefins in good yields (average 75% per step) with excellent functional group tolerance and chemo- and stereoselectivities
使用钯 (II) 和高价碘助催化,开发了一种温和的(35 °C,无布朗斯台德酸)串联瓦克氧化-末端烯烃脱氢反应。该反应直接从易于获得的末端烯烃中得到直链芳基和烷基 α,β-不饱和酮,收率良好(每步平均 75%),具有优异的官能团耐受性以及化学和立体选择性。人们发现高价碘助催化剂对于脱氢至关重要,但作为化学计量氧化剂并不有效。

(EN) Certain cyclohexyl and cyclohexenyl aliphatic alcohols and ketones are potent attractants for $i(Dacus latifrons), the Malaysian fruit fly. By attracting adult males to field traps, the compounds provide a means for detecting, monitoring, and controlling this agricultural pest.(FR) Certains alcools et cétones aliphatiques de cyclohexyle et de cyclohexényle sont de puissants attractifs pour $i(Dacus Latifrons), diptère malais. De par leur pouvoir attractif sur des mâles adultes dans des pièges situés sur le terrain, les composés constituent un moyen de détection, de contrôle, et de régulation de ce ravageur des cultures.
