  • Branched‐Selective Direct α‐Alkylation of Cyclic Ketones with Simple Alkenes
    作者:Dong Xing、Xiaotian Qi、Daniel Marchant、Peng Liu、Guangbin Dong

    日期:2019.3.22
    Herein, we describe an intermolecular direct branched‐selective α‐alkylation of cyclic ketones with simple alkenes as the alkylation agents. Through an enamine‐transition metal cooperative catalysis mode, the α‐alkylation is realized in an atom‐ and step‐economic manner with excellent branched selectivity for preparing β‐branched ketones. Employment of a pair of bulky Brønsted acid and base as additives
    在本文中,我们描述了以简单烯烃作为烷基化剂的环状酮的分子间直接支链选择性α-烷基化。通过烯胺-过渡金属的协同催化模式,α-烷基化反应可在原子经济和分步经济的方式下实现,并具有出色的支化选择性,可制备β-支化的酮。使用一对笨重的布朗斯台德酸和碱作为添加剂有助于提高效率。已获得有希望的对映选择性(74%  ee)。实验和计算机制研究表明,通过烯烃迁移插入Ir-C键然后CH-H还原消除的途径涉及高支化选择性。

    Radical addition of ketones to alkenes catalyzed by Mn(OAc)2 combined with Co(OAc)2 using dioxygen as oxidant was developed; for instance, the reaction of cyclohexanone with oct-1-ene in the presence of very small amounts of Mn(OAc)2 and Co(OAc)2 under air (1 atm) gave 2-octylcyclohexanone in good selectivity; from styrene, a six-membered cyclic peroxide was isolated in good yield.

    identified the products of thermal decomposition as a function of exposure temperature. Detailed characterizations of products were performed with Fourier transform infrared spectrometry (FTIR), gas chromatography/ mass spectrometry (GC/MS), viscosity experiments and four-ball tests. The results showed that PAO had the lower thermal stability, being degraded at 200°C different from 300°C for DE. The
    在氧化热解条件下,研究了两种合成润滑基础油聚α-烯烃(PAO)和二酯(DE)的热降解。该研究的主要目的是表征它们在模拟“发动机”条件下的行为,即比较热稳定性并确定热分解产物与暴露温度的关系。使用傅里叶变换红外光谱(FTIR),气相色谱/质谱(GC / MS),粘度实验和四球测试对产品进行详细的表征。结果表明,PAO具有较低的热稳定性,在200°C时降解,与DE的300°C不同。降解还影响了润滑油的摩擦学性能。在两种润滑剂的热降解过程中,发现了几种副产物。根据GC / MS分析的结果,大多数PAO产物由烷烃和烯烃组成,而DE样品中检测到更多的含氧有机化合物。根据实验结果讨论了相关的反应机理。
