• Phosphine-free palladium-catalysed direct 5-arylation of imidazole derivatives at low catalyst loading
  作者：Julien Roger、Henri Doucet

  日期：2009.11

  The regioselective 5-arylation of imidazole derivatives with aryl bromides using a low loading of a phosphine-free palladium catalyst gives a simple and economic access to the corresponding 5-arylimidazoles. The choice of the base and of the solvent was found to be crucial to form these products in high yields. Using KOAc as the base, DMAc as the solvent and only 0.5–0.01 mol % Pd(OAc)2 as the catalyst

  使用低负荷的无膦钯催化剂，将咪唑衍生物与芳基溴进行区域选择性的5-芳基化，可简单而经济地获得相应的5-芳基咪唑。发现碱和溶剂的选择对于以高收率形成这些产物是至关重要的。使用KOAc作为碱，使用DMAc作为溶剂，仅使用0.5-0.01 mol％Pd（OAc）2作为催化剂，可以以中等到良好的收率得到目标产物，并带有多种芳基溴化物。芳基溴上的取代基如氟，三氟甲基，甲酰基，乙酰基，丙酰基，酯或腈是可以接受的。也可以使用立体上稠合的芳基溴化物或杂芳基溴化物。咪唑衍生物上取代基的性质对产率有重要影响。
• Palladium-catalysed direct arylations of heteroaromatics using more eco-compatible solvents pentan-1-ol or 3-methylbutan-1-ol

  The palladium-catalysed direct coupling of aryl halides with heteroaromatics in greener solvents than DMF or DMAc, which are often employed for such couplings, would be a considerable advantage for both industrial application and sustainable development. We observed that a range of aryl bromides undergoe coupling via C-H bond activation/functionalisation reaction of thiazoles or imidazoles in moderate to good yields using pentan-1-ol or 3-methylbutan-1-ol as the solvents. Pentan-1-ol and 3-methylbutan-1-ol are less toxic than DMF or DMAc, moreover they are bioresources as they can be obtained by fermentation. Therefore, these reaction conditions are certainly more eco-compatible than those generally employed for such couplings. (C) 2011 Elsevier Ltd. All rights reserved.
• Developing Bis(imino)acenaphthene-Supported <i>N</i>-Heterocyclic Carbene Palladium Precatalysts for Direct Arylation of Azoles

  On the basis of the strategy of developing highly efficient protocol for Pd-catalyzed cross-coupling reactions, a series of bulky bis(imino)acenaphthene (BIAN)-supported Pd-PEPPSI complexes were synthesized, characterized, and applied in direct arylation of azoles. The effect of backbone and N-moieties on NHCs was evaluated, and the reaction conditions were optimized. It was found that the bulky Pd-PEPPSI complexes could be successfully employed in cross-coupling of (hetero)aryl bromides with azoles at a low palladium loading of 0.5-0.05 mol % under aerobic conditions, demonstrating the ease of manipulation without glovebox and handling of solvents.
