A facile synthesis of 2,4,6-trichloroborazine from boron trichloride–dimethylsulfide complex and ammonium chloride

2,4,6-Trichloroborazine has been recognized as a desirable monomer for the preparation of high-performance boron nitride fibers through polymer derived ceramics route. So a high yield and facile synthesis of 2,4,6-trichloroborazine is essential in practice. Using boron trichloride–dimethylsulfide complex ((CH3)2S·BCl3) and ammonium chloride (NH4Cl) as starting materials and toluene (C6H5CH3) as solvent, the synthesis of 2,4,6-trichloroborazine to give high yield is reported.
