  Herein, we report a straightforward, environmentally friendly, and controllable palladium/ligand catalytic system to enable reductive/oxidative Heck reactions of cyclic enones with thiophene or furan derivatives via C-H activation. The key to this tunable reaction is the appropriate intercepting thienyl-Pd(II)-enolate during the enolization process. Such a controllable and economic protocol would not

  本文中，我们报道了一种简单，环保且可控制的钯/配体催化体系，可通过CH活化使环烯酮与噻吩或呋喃衍生物发生还原/氧化Heck反应。该可调反应的关键是在烯醇化过程中适当拦截噻吩-Pd（II）-烯醇化物。这种可控且经济的方案不仅将提供构建各种增值的β-杂芳基化的环状酮/烯酮的有效方法，而且还将阐明通过CH活化进行其他共轭加成反应的方法。

• The direct formation of functionalized alkyl(aryl)zinc halides by oxidative addition of highly reactive zinc with organic halides and their reactions with acid chlorides, .alpha.,.beta.-unsaturated ketones, and allylic, aryl, and vinyl halides

  日期：1991.2

  Highly reactive zinc, prepared by the lithium naphthalenide reduction of ZnCl2, readily undergoes oxidative addition to alkyl, aryl, and vinyl halides under mild conditions to generate the corresponding organozinc compounds in excellent yields. Significantly, the reaction will tolerate a spectrum of functional groups on the organic halides. Accordingly, this approach can now be used to prepare a wide variety of highly functionalized organozinc compounds. In the presence of Cu(I) salts, the organozinc compounds cross-couple with acid chlorides, conjugatively add to alpha,beta-unsaturated ketones, and regioselectively undergo S(N)2' substitution reactions with allylic halides. They also cross-couple with aryl or vinyl halides with Pd(0) catalysts.
