  Visible-Light-Promoted Remote C(sp³)–H Amidation and Chlorination

  摘要：

  A visible-light-promoted C(sp(3))-H amidation and chlorination of N-chlorosulfonamides (NCSs) is reported. This remote C(sp(3))-H functionalization can be achieved in weak basic solution at room temperature with as little as 0.1 mol % of a photocatalyst. A variety of nitrogen-containing heterocycles (up to 94% yield) and chlorides (up to 93% yield) are prepared from NCSs. Late-stage C(sp3)H functionalization of complex and biologically important (-)-cis-myrtanylamine and (+)-dehydroabietylamine derivatives can also be achieved with excellent yields and regioselectivity.

  proved also useful as a catalyst in numerous organic reactions. Commercial availability and lower cost than precious metal complexes, make cobalamin an attractive candidate for a broader use as a benign Co-catalyst. Herein, the vitamin B12-catalyzed dicarbofuntionalization of bromoalkenes with electrophilic olefins is reported leading to substituted pyrrolidines and piperidines in decent yields after only

  维生素B 12在酶促转化中起关键作用。事实证明，这种天然化合物还可用作许多有机反应的催化剂。商业可获得性和比贵金属络合物更低的成本，使钴胺素成为广泛用作良性助催化剂的诱人候选物。在本文中，据报道维生素B 12催化的具有亲电烯烃的溴代烯烃的二碳甲酰化作用导致在光照射下仅15分钟后以适当的产率产生取代的吡咯烷和哌啶。

  irradiation in the presence of catalytic amounts of [(DPEphos)(bcp)Cu]PF6 and an amine, a range of unactivated aryl and alkyl halides were shown to be smoothly activated through a rare Cu(I)/Cu(I)*/Cu(0) catalytic cycle. This complex efficiently catalyzes a series of radical processes, including reductions, cyclizations, and direct arylation of arenes.

  This work illustrates a reductive cross-electrophile coupling protocol for trifluoromethylation of alkyl iodides under Cu-catalyzed/Ni-promoted reaction conditions. The use of diboron esters as the terminal reductant allows the effective generation of the alkyl–CF3 products with excellent functional group tolerance and broad substrate scope. A mechanism involving a reaction of alkyl–Cu with Togni’s

  Let the sunshine in! Unactivated alkyl and aryl bromides underwent a light‐enabled reductive radical cyclization in the presence of a dimeric phosphine–gold complex as a photocatalyst (see scheme; X=C(CO2Et)2, NR, O). Sunlight can be used as the energy source for this simple and efficient radical reaction, which does not require potentially hazardous and toxic chemical reagents, such as organostannanes

  让阳光照进来！未活化的烷基和芳基溴化物在二聚膦-金络合物作为光催化剂的情况下进行了光活化的还原性自由基环化反应（见方案； X = C（CO 2 Et）2，NR，O）。阳光可以用作此简单有效的自由基反应的能源，该自由基反应不需要潜在危险和有毒的化学试剂，例如有机锡和化学引发剂。

  5-Exo-trig radical reductive cyclization reactions of bromoacetals are catalyzed by iron in the presence of the reducing agent NaBH4. Both iron(II) and iron(III) were found to effectively mediate these reactions. As shown by cyclic voltammetry, iron(III) can be reduced to an iron(II) precatalyst before passing through an identical reaction mechanism in which monoelectronic activation of the substrate

  在还原剂NaBH 4的存在下，铁催化了溴乙缩醛的5- Exo- trig自由基还原环化反应。发现铁（II）和铁（III）均可有效介导这些反应。如循环伏安法所示，在通过相同的反应机理之前，铁（III）可以还原为铁（II）预催化剂，在该反应机理中，阴离子氢化铁（I）络合物会发生底物的单电子活化。进一步的研究已经确定，底物（碘衍生物与溴衍生物）和预催化混合物均对确定反应结果具有决定性作用。
