    Naphthalene-catalysed lithiation of allylic and benzylic mesylates: a new method for allyl, methallyl, and benzyl lithium
    摘要:
    The reaction of allylic or benzylic mesylates (1) with an excess of lithium powder and a catalytic amount of naphthalene (4 mol %) in THF at -78-degrees-C leads to a solution of the corresponding organolithium derivatives, which by treatment with different electrophiles yield the expected products 2-7. As an alternative route, the process can be carried out at 0-degrees-C by adding the corresponding mesylate together with the electrophile to a suspension of the activated lithium in THF, in a Barbier-type reaction.

    Changing places: Intramolecular B(pin)/H exchange took place in the presence of a platinum–phosphane catalyst, giving synthetically useful cis‐β‐methyl‐substituted alkenylboronates stereoselectively (see scheme; B(pin)=4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolan‐2‐yl).
    变化的地方:分子内的B(pin)/ H交换是在铂-膦催化剂存在下进行的,立体选择性地合成了有用的顺式-β-甲基取代的烯基硼酸酯(参见方案; B(pin)= 4、4、5, 5-四甲基-1,3,2-二氧杂硼硼烷-2-基)。

    streching bONds, corresponding to C  CH2 and C  CD2 groups in equilibrating allylic isomers. The methylene resonances in the 13C NMR spectra of allylmagnesium bromide and chloride and methallylmagnesium bromide are broadened at low temperatures by an exchange process which appears to be the interconversion between the classical unsymmetrical allytic structures. Analogous changes are seen in the spectrum
    烯丙基-和甲基烯丙基-d 2-溴化镁的红外光谱具有两个双键拉伸键,对应于平衡烯丙基异构体中的CCH 2和C 2 CD 2基团。13中的亚甲基共振烯丙基溴化镁和氯化物以及甲基烯丙基溴化镁的13 C NMR光谱在低温下通过交换过程扩大,这似乎是经典不对称解析结构之间的相互转化。在1,3-二甲基烯丙基氯化镁的光谱和烯丙基溴化镁的质子NMR光谱中可以看到类似的变化。交换的速率常数和激活参数已从线宽确定。与格利雅试剂不同,二甲基镁在四氢呋喃中的亚甲基共振在降低的温度下不会显着加宽,并且氘代试剂在红外光谱中没有两个明显的双键拉伸带。

    derived from arenes of high reduction potential (biphenyl, naphthalene) and Li(s) can carbometallate propene, isobutene or norbornene among other alkenes, in an intermolecular fashion. This reaction runs at room temperature to afford partially dearomatized alkylated aryl anions that are susceptible to further functionalization by electrophilic capture. This form of reactivity, typical of the arene dianion
    源自具有高还原电位的芳烃(联苯、萘)和 Li(s)的二价阴离子可以以分子间的方式将丙烯、异丁烯或降冰片烯等烯烃进行碳金属化。该反应在室温下进行以提供部分脱芳构化的烷基化芳基阴离子,这些阴离子易于通过亲电捕获进一步官能化。这种形式的反应性,典型的芳烃二价阴离子,与这些配合物显示的特定碱金属样反应性不同,提供了区域和在许多情况下立体控制的产品。DFT 计算有助于确定该反应的区域化学结果,其中涉及一些最便宜的有机起始材料。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
