Synthesis of Aromatic Polyketones Bearing 1,1'-Binaphthyl-2,2'-dioxy Units through Suzuki-Miyaura Coupling Polymerization
Palladium nanocluster-catalyzed Suzuki-Miyaura coupling polymerization of 2,2'-bis(iodobenzoylphenoxy)-1,1'-binaphthyls 2 with aromatic diboric acid diesters 3 proceeded smoothly, affording 1,1'-binaphthyl-2,2'-dioxy-bearing aromatic polyketones 4. The resulting polyketones 4 have excellent thermal stability and solubility in typical organic solvents.
