• Recent Advances in Electrophilic CF3-Transfer Using Hypervalent Iodine(III) Reagents
  作者：Iris Kieltsch、Patrick Eisenberger、Kyrill Stanek、Antonio Togni

  DOI：10.2533/chimia.2008.260

  日期：——

  The development of new methodologies for an efficient introduction of CF3 groups into complex molecules constitutes one of the most challenging tasks of modern organic chemistry. Recently, we reported the access to a new class of electrophilic CF3-transfer reagents based on hypervalent iodine. The versatile application of these reagents to C-centred nucleophiles, such as ?-keto esters, silyl enol ethers and ?-nitro esters, as well as to thiols and primary and secondary phosphines is described. Experiments with phenols afforded corresponding trifluomethylethers in very low yields.

  first time. It was shown to react under phase-transfer catalysis conditions with 2-nitropropane anion by an SRN1 mechanism to give excellent yield of isopropylidene derivative formed from a base-promoted nitrous acid elimination of C-alkylation product. Extension of this SRN1 reaction to various nitronate anions led to a new class of 3-nitroimidazo[1,2-b]pyridazine derivatives bearing a trisub-stituted

  aromatic amines is of continuous interest in chemistry. An exceptionally versatile three‐component reaction that directly transforms inexpensive nitro compounds, boronic acids, and trialkyl phosphites into tertiary aromatic amines has been realized. The reaction tolerates alkyl and aryl substituents on the nitro and boronic acid moieties, as well as functionalized phosphites. No transition‐metal catalysis

  nickel(0), rhodium(i), ruthenium(0) and iron catalysts under conditions finely tuned for specific, electronically activated substrates, sometimes assisted by chelating functional groups or ring strain. By adopting a redox-neutral strategy involving palladium(ii)-catalysed C–H activation followed by β-heteroatom/carbon elimination, we describe here a catalytic method to activate alkyl C(sp3)–oxygen, nitrogen

  化学家从简单的起始原料合成结构复杂的高价值有机分子的能力受到选择性激活和功能化强烷基C（sp 3）共价键的方法的限制。最近的活动集中在通过低价，富电子的过渡金属的氧化加成的机理范式来激活丰富的C-O，C-N和C-C键。该方法通常在针对特定的电子活化底物进行微调的条件下使用镍（0），铑（i），钌（0）和铁催化剂，有时可通过螯合官能团或环应变来辅助。通过采用涉及钯的氧化还原中性策略（二）催化的C–H活化，然后去除β-杂原子/碳，我们在此描述了一种催化方法，该方法以高区域选择性活化烷基C（sp 3）–氧，氮，碳，氟和硫键。生成的钯（ii）结合的烯烃的直接加氢官能化导致形式化的官能团复分解。该方法用于氨基酸的提纯，具有完全的区域选择性和对映体过量的中等至高保留率。低应变杂环经过强键活化和取代，产生开环产物。
