Technology Process of tetra-p-tolyldibismuthane

There total 1 articles about tetra-p-tolyldibismuthane 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: 45.0%

bis(4-methylphenyl)bismuth bromide (34176-68-6) → tetra-p-tolyldibismuthane (114245-28-2)

Guidance literature:

With Na; In ammonia; byproducts: NaBr; NH3 (liquid); fast condensation of NH3 onto Bi compd., -78°C; stirring; holding at -50°C, 1h; carefully evapn.; extn. (ice-cold CH2Cl2, -30°C); placing soln. on solid CO2, 3h; decantation; washing residue (several times with pentane at -30°C); drying (vac., -30°C);

Reference yield: 94.0%

tetra-p-tolyldibismuthane (114245-28-2) + p-benzoquinone (106-51-4) → 1,4-bis(di-p-tolylbismuthoxo)benzene (114245-31-7)

Guidance literature:

In dichloromethane; react. of p-benzoquinone with Bi compd. soln., -20°C, 1 min; addn. of pentane; storage at -30°C; filtration at 0°C; reducing volume; addn. of pentane; placing on solid CO2, overnight; decantation, washing (several times with ice-cold pentane); drying (vac.); elem. anal.;

Reference yield: 92.0%
