首次报道了未活化的末端烯烃的区域发散性氧硼化反应,使用醇铜作为催化剂,双(频哪醇)二硼[[Bpin)2 ]作为硼源,和(2,2,6,6-四甲基哌啶-1-基)氧基(TEMPO)作为氧气源。该反应与各种官能团相容。通过在铜上选择合适的配体可以选择性地产生两种区域异构体。该产品可以用作用于各种其他官能化一个关键前体,并且净过程如carbooxygenation,aminooxygenation,和烯烃的双加氧可后的C来实现乙键变换。机理研究表明,该反应涉及以下步骤:1)CuO t Bu与(Bpin)2之间的重金属化产生硼铜物种;2)烯烃的区域发散性硼基富集;3)氧化由此生成的CCu键以生成烷基。4)通过TEMPO捕获得到的烷基。

example of a boryl-Heck reaction using an electrophilic boron reagent. This palladium-catalyzed process allows for the conversion of terminal alkenes to trans-alkenyl boronic esters using commercially available catecholchloroborane (catBCl). In situ transesterification allows for rapid access to a variety of boronic esters, amides, and other alkenyl boron adducts.
