  A mild, metal-free, and absolutely para-selective bromination of aniline derivatives has been developed in excellent yields, wherein the organic dye Eosin Y is employed as the bromine source in company with Selectfluor. Neither air nor moisture sensitive, this facile reaction proceeds smoothly at room temperature and completes within a short time. Mechanistic studies indicate a radical pathway; therefore

  The solvent-free, palladium-catalysed reaction of anilides with CuCl2 in the presence or absence of copper acetate yields ortho-chlorinated anilides in good to excellent yields, even on a large scale (100 mmol). By contrast, the equivalent reactions with copper bromide, either solvent free or in 1,2-dichloroethane, in the presence or absence of palladium, under air or inert conditions, gave the products

  DOI：10.1002/ejoc.201801058

  日期：2018.11.25

  A general para‐selective C‐H functionalization was achieved via a steric control strategy. Para‐iodo, bromo, chloro, nitro, and trifluormethyl aniline derivatives were prepared via in situ generated, bulky hypervalent iodinium reagents in as little as 10 min. Products can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work‐up

  作者：Dipannita Kalyani、Allison R. Dick、Waseem Q. Anani、Melanie S. Sanford

  DOI：10.1016/j.tet.2006.06.075

  日期：2006.12

  Palladium-catalyzed ligand directed C–H activation/halogenation reactions have been extensively explored. Both the nature of the directing group and the substitution pattern on the arene ring of the substrate lead to different reactivity profiles, and often different and complementary products, in the presence and absence of the catalyst.

  钯催化的配体定向的C–H活化/卤化反应已得到广泛研究。在存在和不存在催化剂的情况下，导向基团的性质和底物的芳环上的取代图案均导致不同的反应性分布，并且常常导致不同的和互补的产物。

  日期：2018.12

  An effective method has been developed for Rh(III)‐catalyzed direct vinylation of arenes to give functionalized styrenes, using vinyltriethoxysilane as a convenient and inexpensive vinyl source. A wide variety of substrates, including 1‐aryl‐2‐pyrrolidinones, anilines, benzamides and ketones, were compatible with this reaction. Moreover, this method can be applied to the two‐step synthesis of functionalized
