  • Radical Allylation, Vinylation, Alkynylation, and Phenylation Reactions of α-Halo Carbonyl Compounds with Organoboron, Organogallium, and Organoindium Reagents

    reactions of α-halo carbonyl compounds with alkenylindium proceeded via a radical process in the presence of triethylborane. Unactivated alkene moieties and styryl groups were introduced by this method. The carbon-carbon double bond geometry of the alkenylindiums was retained during the alkenylation. Preparation of an alkenylindium via a hydroindation of 1-alkyne and subsequent radical alkenylation established
    发现烯丙基镓和铟试剂可介导 α-碘或 α-溴羰基化合物的自由基烯丙基化反应。在三乙基硼烷的存在下,用由烯丙基氯化镁和三氯化镓制备的烯丙基镓处理溴乙酸苄酯,以极好的收率提供了4-戊烯酸苄酯。添加水作为助溶剂提高了烯丙基化产物的产率。烯丙基铟试剂也是有用的并且可以代替镓试剂。二烯丙基硼烷试剂可以以良好的产率烯丙基化 α-碘酯。在三乙基硼烷存在下,α-卤代羰基化合物与烯基铟的烯基化反应通过自由基过程进行。通过该方法引入了未活化的烯烃部分和苯乙烯基。烯基化过程中保留了烯基铟的碳-碳双键几何结构。通过 1-炔烃的氢化和随后的自由基烯基化制备烯基铟建立了一种有效的一锅法。本文公开了用有机铟试剂进行的自由基炔基化和苯基化。

    An allylgallium reagent is found to be effective for radical allylation of α-iodo or α-bromo carbonyl compounds. Treatment of benzyl bromoacetate with allylgallium, prepared from allylmagnesium chloride and gallium trichloride, in the presence of triethylborane in THF provided benzyl 4-pentenoate in good yield. The addition of water as a cosolvent improved the yields of allylated products. It was revealed
