Technology Process of Dimesitylborane

There total 3 articles about Dimesitylborane 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: 37.0%

K(1+)*{BH2(C6H2(CH3)3)2}(1-)=K{BH2(C6H2(CH3)3)2} + methyl iodide (74-88-4) → dimesitylboron fluoride (51458-06-1)

Guidance literature:

In tetrahydrofuran; hydroborate in THF is cooled to 0°C and MeI is added with stirring, mixt. is allowed to warm to room temp. with stirring over 2 h, the suspension then left to settle; filtn.,evapn., recrystn. from monoglyme under Ar;
