  含不饱和原取代基的芳基环化的机理

  摘要：

  由三丁基锡烷与含不饱和邻位取代基的芳基碘化物相互作用而产生的芳基区域特异性地环化，从而提供了对新形成的环外环外包含新形成的自由基中心的产物。已经确定了许多相关基团的相对环化率。该结果与这样的假设相一致：通过半占据的轨道与π*轨道的一个波瓣的主要相互作用形成了用于烯烃键均溶加成的过渡态。

• Selective Approaches to α‐ and β‐Arylated Vinyl Ethers

  Benzyl vinyl ethers have selectively been arylated at either α or β position by fine-tuned Heck-type palladium catalyses. In contrast to previous protocols, no excess of arylating reagent or substrate chelation is necessary. For achieving good yields and high α/β-selectivities various factors determining the catalytic system had to be optimized. The results of DFT computational studies correlate selectivity

  苄基乙烯基醚已通过微调的 Heck 型钯催化剂在 α 或 β 位选择性芳基化。与以前的协议相比，不需要过量的芳基化试剂或底物螯合。为了获得良好的收率和高 α/β-选择性，必须优化决定催化体系的各种因素。DFT 计算研究的结果将选择性与 Pd 中心上的电子丰富度相关联。
• The conversion of 4-oxa-5-hexenyllithiums to 4-alken-1-ols: a novel [1,4]-wittig rearrangement

  corresponding 3-iodoalkyl vinyl ethers (1) by low-temperature lithium - iodine exchange, rearrange in high yield to 4-alken-1-ols (4) when warmed to room temperature. This transformation, which constitutes a [1,4]-Wittig rearrangement, is mediated by 5-exo-trig closure of 2 to a (2-tetrahydrofuranyl)methyllithium (3) followed by spontaneous ring opening to give 4.

  4-氧杂-5-己烯基锂（2），可以由相应的3-碘烷基乙烯基醚（1）通过低温锂-碘交换制得，并以高收率重排为4-烯-1-醇（4）。当加热到室温时。这种转变，这构成了〔1,4〕-Wittig重排，由5 -外-TRIG的闭合介导2的（2-四氢呋喃基）甲基锂（3然后自然开环），得到4。
• Stable Arylpalladium Iodides and Reactive Arylpalladium Trifluoromethanesulfonates in the Intramolecular Heck Reaction

  The reactions of 1-iodo-2-(3-butenyl)benzene and of two side-chain ether analogs with [1,1'-bis(diphenylphosphino)ferrocene](eta(2)-cyclooctatetraene)palladium gave the expected (eta(1)-aryl)-(eta(1)-iodo)palldium adducts, the 2-oxa-3-butenyl complex being characterized by X-ray crystallography. The alkene does not interact directly with palladium. Restricted rotation about the aryl-palladium bond was observed on the NMR time scale in all cases, since the methylene group(s) of the side chain were diastereotopic. The complexes were stable, but on treatment with silver trifluoromethanesulfonate in acetone at low temperature an unstable species was identified by H-1 and P-31 NMR in two of the three cases. Spectral observations were consistent with the formation and subsequent rearrangement of an intermediate along the pathway of an intramolecular Heck cyclisation with structure o-C6H4OC(CH3)(Pd[dppf]OTf).
