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'-
