  We have developed a simple and direct method for the synthesis of aryl ethers by reacting alcohols/phenols (ROH) with aryl ammonium salts (ArNMe3+), which are readily prepared from anilines (ArNR′2, R′=H or Me). This reaction proceeds smoothly and rapidly (within a few hours) at room temperature in the presence of a commercially available base, such as KOtBu or KHMDS, and has a broad substrate scope

  facile synthesis of 1H-indazoles featuring a Cu(OAc)2-catalyzed N–N bond formation using oxygen as the terminal oxidant is described. The reaction of readily available 2-aminobenzonitriles with various organometallic reagents led to o-aminoaryl N–H ketimine species. The subsequent Cu(OAc)2-catalyzed N–N bond formation in DMSO under oxygen afforded a wide variety of 1H-indazoles in good to excellent

  heterogeneous Pd/C used as the catalyst. Treatment of aryl bromides 1 with Zn(CN)2 in the presence of Pd/C, Zn, ZnBr2 and PPh3 in DMA provided aryl nitriles 2 involving those carrying sterically demanding electron-rich substituent in good yields and in highly reproducible manner. The activity of Pd/C is highly dependent on the properties of the Pd/C. Oxidic thickshell type catalyst Pd/C D5 was found

  通过芳基溴化物1a的经典Rosenmund-von Braun反应制备芳基腈2a由于高的反应温度（165°C）和缺乏从大量的2a中分离2a的有效程序而导致收率（61％）差。重金属废物（铜盐）。为了解决这些问题，已经开发了通过使用异质Pd / C作为催化剂，通过芳基溴化物的氰化来实际合成多官能芳基腈的方法。在DMA中存在Pd / C，Zn，ZnBr 2和PPh 3的情况下，使用Zn（CN）2处理芳基溴化物1提供了芳基腈2涉及那些以高收率和高度可复制的方式携带空间要求高的富电子取代基的化合物。Pd / C的活性高度依赖于Pd / C的特性。发现氧化厚壳型催化剂Pd / C D5具有最高的速率加速和产率。至少在反应的初始阶段，使用非均质的Pd / C可能会将Pd固定并分散在催化剂的固体载体上，以确保形成单体Pd络合物而不会沉淀成惰性的Pd黑色。使用稍微过量的Zn（CN）2 （0.6当量）和膦配体
