We report a Ni-catalyzed regioselective α-carbonylalkylarylation of vinylarenes with α-halocarbonyl compounds and arylzinc reagents. The reaction works with primary, secondary and tertiary α-halocarbonyl molecules, and electronically varied arylzinc reagents. The reaction generates γ,γ-diarylcarbonyl derivatives with α-secondary, tertiary and quaternary carbon centers. The products can be readily converted

Arylzinc compounds containing electron-withdrawing groups such as CO2CH3, CON(CH3)2, CN, Br, Cl, or CF3 at ortho position were prepared readily by the ultrasound-promoted reaction of aryl iodides with zinc powder, which were applied to palladium(0)-catalyzed cross-coupling with aryl halides to afford unsymmetrical and multifunctional biaryls in good yields.
含有电子吸引基团(如 CO2 、CON(CH3)2、CN、Br、Cl 或 CF3)在邻位的芳基锌化合物,通过超声促进的芳基碘化物与锌粉的反应容易制备,随后用于钯(0)催化的交叉偶联反应,与芳基卤化物反应,得到不对称且多功能的双芳基化合物,产率良好。
Cr<sup>3+</sup>-Mediated Addition of Arylzincs to Aldehydes
Addition of arylzincs to aldehydes was achieved by making use of the novel transmetallation of arylzincs into Cr3+ compounds. Various α-substituted benzyl alcohols or 3-substituted 1(3H)-isobenzofuranones, containing reactive functional groups, were synthesized in good yields. Me3SiCl exerted beneficial effects on the reaction.
