  A Study of the Regioselectivity of the Radical Addition of "RSAr" Derived from the Photolysis of tert-Homoallyl and tert-Alkyl 4-Nitrobenzenesulfenates to Substituted Allenes and Alkenes

  摘要：

  The regioselectivity of the free radical addition of ''RSAr'' derived from the photolysis of tert-homoallyl and tert-alkyl 4-nitrobenzenesulfenates, followed by beta-scission of the alkoxy radicals to produce the allyl or alkyl radicals R. to 1,1- and 1,3-dimethylallene and acrylonitrile and methyl acrylate has been determined. The regioselectivity of addition of ''RSAr'' to 1,1- and 1,3-dimethylallene occurs by the addition of the arylthiyl radical to the-center carbon atom of the allene chromophore, whereas the regioselectivity of the addition to acrylonitrile and methyl acrylate varies with the nature of the R.. The results are interpreted in terms of the relative reactivities of the pi systems toward radical addition and the relative rates of beta-scission of the intermediate alkoxy radicals versus the rates of addition of the 4-nitrobenzenethiyl radical and R. to the pi systems.

• Transition‐Metal‐Free Three‐Component Synthesis of Tertiary Aryl Amines from Nitro Compounds, Boronic Acids, and Trialkyl Phosphites

  aromatic amines is of continuous interest in chemistry. An exceptionally versatile three‐component reaction that directly transforms inexpensive nitro compounds, boronic acids, and trialkyl phosphites into tertiary aromatic amines has been realized. The reaction tolerates alkyl and aryl substituents on the nitro and boronic acid moieties, as well as functionalized phosphites. No transition‐metal catalysis

  芳族胺的合成在化学上一直受到关注。已经实现了一种极其通用的三组分反应，该反应可将廉价的硝基化合物，硼酸和亚磷酸三烷基酯直接转化为叔芳族胺。该反应容许硝基和硼酸部分上的烷基和芳基取代基以及官能化的亚磷酸酯。不需要过渡金属催化。该方法与其他经典的金属催化合成方法正交，因为它可以容忍卤素的存在，并且还可以合成功能化的化合物，例如α-氨基酯衍生物。

  catalytic intermediate in these reactions may also account for unusual catalyst-controlled site selectivity wherein C–H alkenylation of five-atom heteroarenes can occur under electronic control with thioether ligands even when this necessarily involves reaction at a more hindered C–H bond. The thioether effect also enables short reaction times under mild conditions for many O-, S-, and N-heteroarenes (55 examples)

  已确定硫醚辅助配体可以大大促进O-，S-和N的C–H烯基化-杂芳烃。动力学数据表明，硫醚-Pd催化的反应比经典的无配体系统快800倍之多。此外，机理研究表明，C–H键的裂解是限制周转的步骤，硫醚配位时的速率加速与该关键步骤从中性途径向阳离子途径的变化相关。在这些反应中形成阳离子型，低配位的催化中间体也可能说明了催化剂控制位点的异常，其中五原子杂芳烃的CH链烯基化可以在硫代配体的电子控制下发生，即使这必然涉及在更阻碍了CH键的键合。硫醚效应还使得许多O-，S-和N-杂芳烃（55个实例），包括晚期药物衍生化的实例。

  acceleration when a broader set of sulfoxides is considered. This behaviour is rationalised in terms of the differences in dipolar charge and its solvation between the ground state and transition state for the two types of substrate. The oxidations of cyclic sulfides and sulfoxides also exhibit contrasting behaviour. The reactivity of the sulfides is insensitive to ring strain but is explicable in frontier
