  摘要：

  与高价碘（III）化合物形成鲜明对比的是，等电子溴（III）对应物迄今为止很少被研究。这一知识差距主要归因于λ 3 -溴烷的反应性难以控制，以及从高毒性和腐蚀性的BrF 3前体中制备它们具有挑战性。在这种情况下，我们提出了一种直接且可扩展的方法，通过对具有两个配位六氟-2-羟基丙基取代基的母体芳基溴进行阳极氧化来制备螯合稳定的λ 3 -溴烷。通过电化学方法合成了一系列对位取代的λ 3 -溴烷，其氧化还原电位范围相对于Ag/AgNO 3为1.86 V至2.60 V。我们证明，通过添加路易斯酸或布朗斯台德酸可以释放实验室稳定的溴（III）物质的固有反应性。 λ 3 -溴烷活化的合成效用通过氧化CC、CN和CO键形成反应来例证。

  formation of organozinc reagents and subsequent cross-coupling with aryl halides and activated carboxylic acids is reported. Formation of organozinc reagents is achieved by pumping organic halides, in the presence of ZnCl2 and LiCl, through an activated Mg-packed column under flow conditions. This method provides efficient in situ formation of aryl, primary, secondary, and tertiary alkyl organozinc reagents

  Robust acenaphthoimidazolylidene palladium complexes have been demonstrated as highly efficient and general catalysts for the sterically hindered Suzuki–Miyaura cross-coupling reactions in excellent yields even with low catalyst loadings under mild reaction conditions. The high catalytic activity of these complexes highlights that, besides the “flexible steric bulky” concept, σ-donor properties of

The prominent use of acridinium salts as a sustainable option for photoredox catalysts has driven the development of more robust and synthetically useful versions based on this scaffold. However, more complicated syntheses, increased cost, and limited commercial availability have hindered the adoption of these catalysts by the greater synthetic community. By
