  • Regioselective electrochemical oxidative radical ortho-(4 + 2)/ipso-(3 + 2) cyclization

    of radical species with alkenes/alkynes, the ortho-/ipso-selectivity of the cyclic reaction between radical species (especially alkyl and alkenyl radical) and aryl groups is still ambiguous. Herein, we develop an electrochemically enabled regioselective ortho-(4 + 2)/ipso-(3 + 2) cyclization of alkyl/alkenyl radicals with aryl groups, which provides a series of tetrahydronaphthalene and spirocarbocycle
    在自由基环化反应中实现区域选择性至关重要,但也极具挑战性。尽管鲍德温规则为自由基物种与烯烃/炔烃的加成提供了指导,但自由基物种(特别是烷基和烯基自由基)与芳基之间的循环反应的邻位/本身选择性仍然不明确。在此,我们开发了烷基/烯基与芳基的电化学区域选择性邻位- (4 + 2)/原位-(3 + 2)环化,提供了一系列四氢萘和螺碳环衍生物,表现出广泛的底物范围和功能群体宽容。烷基/烯基自由基是通过Cp 2 Fe介导的丙二酸苄基酯与烯烃和炔烃的电化学氧化自由基加成产生的。该方法避免了化学氧化剂/碱/贵金属的使用、基材的预功能化以及化合物的过度氧化。理论研究表明,有利的相互作用能是促进烯烃优先邻位加成的主导因素;炔烃优选的原位加成区域选择性由畸变能控制。值得注意的是,该策略被视为鲍德温激进环化规则的重要补充。

    A method for producing a solid catalyst component for olefin polymerization produces a novel solid catalyst component for olefin polymerization that achieves excellent olefin polymerization activity and activity with respect to hydrogen during polymerization, and can produce an olefin polymer that exhibits a high MFR, high stereoregularity, and excellent rigidity. The method includes a first step that brings a magnesium compound, a tetravalent titanium halide compound, and one or more first internal electron donor compounds selected from specific aromatic dicarboxylic diesters into contact with each other to effect a reaction, followed by washing, a second step that brings a tetravalent titanium halide compound and one or more second internal electron donor compounds into contact with a product obtained by the first step to effect a reaction, followed by washing, and a third step that brings one or more third internal electron donor compounds into contact with a product obtained by the second step to effect a reaction.
