An original formation of one C–N bond and one C–C bond on the same carbenic center has been developed. This approach involves a copper-catalyzed cross-coupling reaction between 2′-bromo-biaryl-N-tosylhydrazones and different amines leading to 9H-fluoren-9-amine derivatives. This reaction proceeds under mild conditions in glycerol, an inexpensive and environmentally friendly solvent, without adding any
已经开发了在同一羧基中心上一个C–N键和一个C–C键的原始结构。该方法涉及2'-溴-联芳基-N-甲苯磺酰基hydr与不同的胺之间的铜催化的交叉偶联反应,从而产生9 H-芴-9-胺衍生物。该反应在温和的条件下在甘油(一种廉价且对环境友好的溶剂)中进行,而无需添加任何外部配体。
