Ipaktschi and Sharifl reported the palladium-catalyzed synthesis of 2,7-diamino fluorenones by two indirect routes due to the base sensitivity of fluorenones [182]. First, 2,7-dibromofluorene was reacted with secondary amines, and subsequent oxidation of the product formed the diaminofluorenone. Alternatively, reaction of ami-nostannanes derived from secondary amines with 2,7-dibromofluorenone gave yields of the fluorenone ranging from 42 to 58%. Beletskaya has used the DPPF-ligated palladium system to conduct selective monoarylation of ethylene diamine, diethylene triamine, triethylene tetra-amines, and 2,2-dimethyl butane-1,3-diamine [183].

Apart from reactions where Michael addition terminated the process, Gabriele and co-workers have developed a useful and expedient palladium-catalyzed synthesis of 4-aminofuran-2-one 113 starting from three simple starting components, a propargyl alcohol, a dialkyl amine and carbon monoxide [98] (Scheme 44). 

This palladium-catalyzed synthesis is superior to that catalyzed by cobalt in many respects. Both the catalytic efficiency and the attainable yields are considerably higher. Several components.
