  Copper(II)-Mediated Dehydrogenative Cross-Coupling of Heteroarenes

  摘要：

  Cu(OAc)(2)-mediated dehydrogenative cross-coupling between two heteroarenes has been realized in the absence of any other additive. A mechanism involving a formal Cu(II) to Cu(0) route by convergent disproportionation of the copper mediator is proposed and has been evidenced by copper mirror formation during the reaction. This synthetic protocol provides a concise and "green" access to unsymmetrical biheteroarenes bearing structural motifs of substantial utility in organic synthesis.

  镍催化可实现两个杂芳烃之间的氧化性C（sp2）–H / C（sp2）–H交叉偶联反应

  摘要：

  镍可用于促进两个杂芳烃之间的氧化C（sp 2）-H / C（sp 2）-H交叉偶联。反应范围可扩展至芳族羧酰胺作为偶联伴侣。该反应具有很高的官能团相容性和广泛的底物范围。可以循环使用银氧化剂以减少成本和浪费，这对于实际应用非常有用。

  A programmed synthesis of privileged arylthiazoles via sequential C–H couplings catalyzed by palladium or nickel catalysts has been accomplished. This versatile protocol can supply all possible arylthiazole substitution patterns (2-aryl, 4-aryl, 5-aryl, 2,4-diaryl, 2,5-diaryl, 4,5-diaryl, and 2,4,5-triaryl) from an unfunctionalized thiazole platform by 11 distinct synthetic routes. We have generated

  cross‐coupling between two heteroarenes is reported, which exhibits a broad substrate scope and a high tolerance level for sensitive functional groups. When the amount of Co(OAc)2⋅4 H2O is reduced from 6.0 to 0.5 mol %, an excellent yield is still obtained at an elevated temperature with a prolonged reaction time. The method can be extended to the reaction between an arene and a heteroarene. It is worth noting

• One-pot Sequential Direct C–H Bond Arylation of Azoles Catalyzed by [Pd(phen)₂](PF₆)₂: Synthetic Methods for Triarylated Azoles

  Synthetic methods for triarylated azoles containing three different aryl groups via one-pot sequential multiple C-H bond arylations are described. The one-pot sequential diarylation of C5-monoarylated azoles was achieved by the simple sequential addition of two different aryl iodides with a [Pd(phen)(2)]PF6 catalytic system. The one-pot triarylation of N-methylimidazole was achieved by the combination of a previously reported Pd(OAc)(2)-P(2-furyl)(3) system and the present [Pd(phen)(2)]PF6 system. In this case, portionwise addition of aryl halide, base and the catalyst in the final step significantly improved the overall yield of the desired triarylated product These protocols led to triarylated azoles without a loss of efficiency compared to the corresponding previously reported stepwise syntheses via direct C-H bond arylation.
