Technology Process of cis-PdMePh(PMe₂Ph)2

There total 1 articles about cis-PdMePh(PMe₂Ph)2 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: 84.0%

trans-PdBrPh(PMe2Ph)2 (117308-45-9) → cis-PdMePh(PMe2Ph)2 (117308-38-0)

Guidance literature:

With methanol; methyllithium; In diethyl ether; byproducts: MeOLi; under N2, Ar or vac.; addn. of MeLi soln. to a mixt. of trans-PdPh(Br)(PMe2Ph)2 and Et2O, contg. styrene, at -40°C; stirred 1h, 20°C; cooled to -70°C; addn. of Et2O soln. of MeOH (LiOMe); filtered at -30°C; concd. to dryness; dissolved in Et2O/pentane (1:4, -20°C);stirred at -40°C; pptn.; recrystn. from cold Et2O/pentane (4:1, small amount of styrene); pptn.; elem. anal.;
