説明
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 N2═C] 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.
