Technology Process of dimesitylbromoborane

There total 7 articles about dimesitylbromoborane 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: 91.0%

[mesitylcopper]5*toluene + boron tribromide (10294-33-4) → trimesitylborane (7297-95-2) + mesityl boron dibromide + dimesitylbromoborane (612844-47-0)

Guidance literature:

In toluene; under N2; soln. of BBr3 (1.05 equiv) in toluene added dropwise at -78 °C to suspn. of (CuMes)5*toluene in toluene; mixt. stirred at -78 °C for 2 h and then allowed to slowly warm to room temp. overnight; after filtration all volatiles removed under high vac.; crude product purified by distn. under reduced pressure; elem. anal.;
