Ru-Catalyzed Polycondensation of Dialkyl 1,4-Phenylenebis(diazoacetate)
with Dianiline: Synthesis of Well-Defined Aromatic Polyamines Bearing
an Alkoxycarbonyl Group at the Adjacent Carbon of Each Nitrogen in
the Main Chain Framework

Transition-metal-catalyzed
N–H insertion of a diazocarbonyl
compound is applied for polycondensation for the first time to give
a new type of aromatic polyamine. The well-defined polyamines were
obtained by [RuCl2(p-cymene)]2-catalyzed reaction of diethyl 1,4-phenylenebis(diazoacetate) with
dianilines bearing a variety of linkers between two aniline units.
The polycondensation proceeded at 30 °C in CH2Cl2 with 5.0 mol % of the Ru metal to [NH2 or N2C] to afford the products with Mn = 6400–28 300 in moderate to high yield. Ethoxycarbonyl
groups located at an adjacent position to NH imparted solubility to
the polyamines, and their glass transition temperatures can be varied
depending on the linker structure in a range of 88–173 °C.
