Technology Process of (2,5-dimethylphenyl)dichloroborane

There total 8 articles about (2,5-dimethylphenyl)dichloroborane 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: 42.0%

para-xylene (106-42-3) + boron trichloride (10294-34-5) + diborane (19287-45-7) → dichloro-p-tolyl-borane (4250-45-7) + (2,5-dimethylphenyl)dichloroborane (21022-98-0) + (2-methylphenyl)dichloroborane (4250-48-0) + (3-CH3-C6H4)BCl2 (4250-47-9) + hydrogen (1333-74-0)

Guidance literature:

byproducts: boron hydride; High Pressure; under N2; diborane and trihalogen-borane was added to p-xylene at -130°C, then in a closed autoclave the mixture was heated to 130°C; at -195.8°C H2 was removed, at room temp. the residue of trihalogen-borane and diborane were removed;

Reference yield:

para-xylene (106-42-3) + boron trichloride (10294-34-5) → (2,5-dimethylphenyl)dichloroborane (21022-98-0)
