There total 2 articles about 1H-Pyrazole, 1,1'-(diphenylmethylene)bis[3,5-dimethyl- 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%

C26H24MoN4O3 (153606-86-1) + phosphorous acid trimethyl ester (121-45-9) → Mo(CO)3(P(OCH3)3)3 (22261-14-9,15631-24-0,15631-23-9) + diphenylbis(3,5-dimethylpyrazol-1-yl)methane (153625-25-3)

Guidance literature:

In dichloromethane; addn. of P(OMe)3 to a stirred soln. of Mo-complex dissolved in CH2Cl2, colour changes from orangered to pale yellow, reaction for 6 h; removal of solvent and excess of P(OMe)3 under vac., extn. with hexane, removal under reduced pressure gives Mo-complex, recrystn. of remaining solid residue from CH2Cl2/hexane gives ligand;
