Technology Process of Cl₄WNC₆H₄CH₃

There total 2 articles about Cl₄WNC₆H₄CH₃ 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: 85.0%

tungsten oxytetrachloride (160797-03-5,13520-78-0) + p-Tolylisocyanate (622-58-2,374675-64-6) → Cl4WNC6H4CH3 (111053-11-3)

Guidance literature:

In benzene; isocyanate and WOCl4 were heated in refluxing benzene for 18 h under N2; crystals were filtered from the cooled soln., washed with benzene, and dried in vacuo; elem. anal.;

Reference yield:

tungsten(VI) oxychloride + p-Tolylisocyanate (622-58-2,374675-64-6) → Cl4WNC6H4CH3 (111053-11-3)

Guidance literature:

In benzene; byproducts: CO2; addn. of isocyanate to WOCl4 suspension, refluxing 18 h; filtration of hot soln., crystn., washing (pentane), drying (vac.), further batch obtained by concn. of mother liquor, recrystn. (toluene);
