実験手順

B,B′,B″-trichloroborazine (15 g) was dissolved into sufficiently dewatered toluene (100 mL) and a mixture solution of n-hexyl amine (37 g), triethyl amine (25 g) and toluene (100 mL) was dropped over 1 hour at room temperature. After completion of the drop-wise addition, the solution was stirred at 25° C. for 3 hours and further at 60° C. for 3 hours. An amine-HCl salt generated was removed by filtration, followed by removal of the solvent and unreacting amine under reduced pressure to obtain B,B′,B″-tris(hexylamino)borazine as yellow viscous liquid (30 g). Thus obtained compound was further stirred in xylene at 130° C. for 3 hours to proceed polycondensation reaction. After the reaction, the solvent is removed under reduced pressure to obtain a borazine ring-containing compound 2.
