  Synthesis of biaryls via the Suzuki-Miyaura coupling (SMC) reaction using nitroarenes as an electrophilic coupling partners is described. Mechanistic studies have revealed that the catalytic cycle of this reaction is initiated by the cleavage of the aryl-nitro (Ar-NO2) bond by palladium, which represents an unprecedented elemental reaction.

  作者：Zhirong Li、Yonggang Peng、Tao Wu

  日期：2021.2.5

  The palladium-catalyzed α-arylation of ketones with readily available nitroarenes and nitroheteroarenes provides access to useful α-aryl and α-heteroaryl ketones. The use of the Pd/BrettPhos catalysts was critical to achieve high efficiency for these transformations, whereas other catalysts led to decreased yields or no conversions. The intramolecular type substrate was also applied in this methodology

• Deprotection of Acetals and Ketals in a Colloidal Suspension Generated by ­Sodium Tetrakis(3,5-trifluoromethylphenyl)borate in Water
  作者：Shiuh-Tzung Liu、Chih-Ching Chang、Bei-Sih Liao

  DOI：10.1055/s-2007-968009

  日期：2007.2

  Deprotection of acetals and ketals can be achieved by ­using sodium tetrakis(3,5-trifluoromethylphenyl)borate (NaBArF 4) as the catalyst in water at 30 °C. For example, a quantitative con­version of 2-phenyl-1,3-dioxolane into benzaldehyde was accomplished within five minutes by using this sodium salt (0.1 mol%) in water.

  使用四(3,5-三氟甲基苯基)硼酸钠（NaBArF 4）作为催化剂，在30°C的水中可以实现缩酮和缩醛的去保护。例如，通过在水中使用这种钠盐（0.1摩尔%），2-苯基-1,3-二氧戊环在五分钟内实现了定量的转化为苯甲醛。
