  The preparation and in vitro aromatase inhibitory activity of a wide variety of heterocyclic (4,4'-dichlorodiphenyl)methanes and -methanols are described. The choice of the two diaryl-bearing moieties as a vehicle for the evaluation of the heterocycles was made by the comparison of series of imidazole and pyridine-derived compounds with similar pyrimidine compounds reported previously.

  C–H bonds has become a dominant research theme in the past decade as an approach to efficient synthesis. However, the incorporation of carbon monoxide into such reactions to form valuable ketones has to date proved a challenge, despite its potential as a straightforward and green alternative to Friedel–Crafts reactions. Here we describe a new approach to palladium-catalysed C–H bond functionalization

  在过去的十年中，作为有效合成方法的一种金属催化方法的开发已成为一个主要的研究主题，以使C-H键惰性化。然而，迄今为止，将一氧化碳掺入此类反应以形成有价值的酮已证明是一项挑战，尽管它有潜力作为Friedel-Crafts反应的直接和绿色替代品。在这里，我们描述了一种新的钯催化的C–H键官能化方法，其中一氧化碳用于驱动高能亲电试剂的生成。这提供了一种方法，可以将金属催化的C-H官能化（稳定和可用的试剂）和亲电酰化（广泛的范围和选择性）的有用特征耦合在一起，并从芳基碘化物，CO和芳烃简单地合成酮。尤其，该反应以分子间方式进行，没有导向基团，并且钯催化剂的负载量非常低。机理研究表明，该反应通过强效的芳基三氟甲磺酸酯亲电子试剂的催化积累而进行。
