Trichloro-trimethyl-borazine TCTMB

The monomer tri-isocyanto-trimethyl-borazine (TITMB) was synthesized from trichloro-trimethyl-borazine (TCTMB) according to the method reported in the literature [12]. The Intermediate TCTMB was synthesized via a modification of the procedure of Brown and Laubengayer [13]. Methyl-amine hydrochloride and excess of BCI3 were refluxed in chlorobenzene for 6h and then maintained for 16h at 80°C. The reaction mixture was filtered warm, vacuum dried and subsequently sublimed under reduced pressure. A slight increase in yield (12%) of pure TCTMB was achieved.
