example of directed C–H activation for azulene is reported. A variety of 2-arylazulenes are obtainable exclusively from 1-azulene carboxylic acids, with yields of up to 82%. Some heteroaryl groups such as pyridine and thiophene are also tolerated in the reaction. The efficacy of the reaction is found to be highly dependent on the conditions, with a phosphate base and a bulky carboxylic acid being key
据报道,第一个例子是直接对苯丙胺进行CHH活化。各种2-芳基azulenes只能从1-azulene羧酸中获得,产率最高可达82%。在反应中还容许一些杂芳基,例如吡啶和噻吩。发现反应的效率高度依赖于条件,其中磷酸根和大体积的羧酸是关键添加剂。
