A novel iridium‐catalyzed intermolecularcoupling reaction of primary alcohols or aldehydes with 2‐alkynes was successfully achieved with high regioselectivity to give hydroacylation products such as α,β‐unsaturatedketones in good yields. The mechanistic investigation of the reaction strongly indicated that the coupling proceeds through the initial formation of homoallylic alcohols followed by dehydrogenation
A Convenient Method for Preparing Aromatic α,β-Unsaturated Ketones from α,β-Unsaturated Acyl Chlorides and Arylboronic Acids via Suzuki-Miyaura Type Coupling Reaction
Aromaticα,β-unsaturatetl ketones are synthesized efficiently by palladium-catalyzed cross-coupling reaction of arylboronic acids with α,β-unsaturated acyl chlorides in the presence of K 3 PO 4 hydrate in toluene.
在甲苯中,K 3 PO 4 水合物存在下,通过钯催化的芳基硼酸与 α,β-不饱和酰氯的交叉偶联反应有效地合成了芳香族 α,β-不饱和酮。
