A Suzuki cross-coupling reaction of hindered 2-bromo-1-trimethylsilylethynylbenzenes with 1-naphthaleneboronic acid yielding (2-ethynylphenyl)naphthalenes has been achieved. Their subsequent cyclization was carried out, giving benzo[c]phenanthrenes, without the use of photochemical procedures.
已实现受阻2-溴-1-三甲基甲硅烷基乙炔基苯与1-萘硼酸的Suzuki交叉偶联反应,生成(2-乙炔基苯基)萘。他们随后进行环化反应,得到苯并[ c ]菲,而无需使用光化学方法。
Synthesis of Polycyclic Aromatic Hydrocarbons Decorated by Fluorinated Carbon Acids/Carbanions
The reaction of biphenyl-alkynes with in situ generated Tf2C=CH2 followed by neutralization gave polycyclicaromatichydrocarbons (PAHs) decorated by a highly stabilized carbanionic functionality. Thus obtained PAHs showed improved solubility in both aqueous and organic solvents.
的反应联苯炔烃与原位产生的TF 2 C = CH 2,然后中和,得到由高度稳定的负碳离子的功能的装饰多环芳香烃(PAHs)。由此获得的多环芳烃在水性和有机溶剂中均显示出改善的溶解度。
