Technology Process of B-TRIBROMOBORAZINE

There total 7 articles about B-TRIBROMOBORAZINE which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 99.0%

2,4,6-triethyl-borazine (7443-22-3) + boron tribromide (10294-33-4) → 2,4,6-tribromo-cyclotriborazane (13703-88-3) + Br2(CH3CH2)B3N3H3 (136237-57-5)

Guidance literature:

In dichloromethane; addn. of BBr3 to a stirred soln. of the borazine in CH2Cl2 at -10°C over 1 h, warming to room temp., refluxing for 1 h; filtn., evapn. of volatiles under reduced pressure, sublimation under vacuum (40-50°C bath temp.), elem. anal.;

Reference yield: 42.0%

ammonium bromide + boron tribromide (10294-33-4) → 2,4,6-tribromo-cyclotriborazane (13703-88-3)

Guidance literature:

Reference yield:

ammonium bromide + boron tribromide (10294-33-4) → 2,4,6-tribromo-cyclotriborazane (13703-88-3) + hydrogen bromide (10035-10-6,12258-64-9)
