Technology Process of 1,2,4,3,5-Trithiadiborolane, 3,5-dibromo-

There total 2 articles about 1,2,4,3,5-Trithiadiborolane, 3,5-dibromo- 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:

boron tribromide (10294-33-4) → sulfur (10544-50-0) + 3,5-dibromo-1,2,4-trithia-3,5-diborolane (13863-77-9)

Guidance literature:

With polysulfanes; In carbon disulfide; byproducts: HBr; dropping H2S(n) /n nearly 6/ into BBr3; very good yield;

Reference yield:

disulfane (23550-45-0) + boron tribromide (10294-33-4) → sulfur (10544-50-0) + 3,5-dibromo-1,2,4-trithia-3,5-diborolane (13863-77-9)

Guidance literature:

In carbon disulfide; byproducts: HBr; dropping H2S2 into BBr3; very good yield;

Reference yield: 46.0%

3,5-dibromo-1,2,4-trithia-3,5-diborolane (13863-77-9) + benzylidene phenylamine (538-51-2) → 3,5-dibromo-4-phenyl-1,2,4,3,5-dithiazadiborolidine (94397-75-8)

Guidance literature:

In tetrachloromethane; dropwise addn. of equimolar amt. of the azomethine soln. to stirred soln. of the diborolane in CCl4 (N2, room temp., 15 min), refluxed (20 h); evapn. (high vac.), distn.; oil; elem. anal.;
