Technology Process of Bromodimethylsulfonium bromide

There total 2 articles about Bromodimethylsulfonium bromide 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:

trimethylsilyl bromide (2857-97-8) + dimethyl sulfoxide (67-68-5,8070-53-9) → Hexamethyldisiloxane (107-46-0) + dimethylbromosulphonium bromide (50450-21-0)

Guidance literature:

In hexane; for 0.333333h; Ambient temperature;

Reference yield:

Acetyl bromide (506-96-7) + dimethyl sulfoxide (67-68-5,8070-53-9) → dimethylsulfide (75-18-3) + bromomethyl methyl sulfide (24276-77-5) + (methylthio)methyl acetate (16437-69-7) + acetic anhydride (108-24-7) + dimethylbromosulphonium bromide (50450-21-0) + acetic acid (64-19-7,77671-22-8)

Guidance literature:

In dichloromethane; at -8 ℃; Product distribution; further temperature, also with SbCl₅; half-life time;

Reference yield: 96.0%
