Splet03. dec. 2024 · The PdCl2-Fe3O4@SiO2-2P catalyst exhibited an enhanced catalytic activity for Heck, Suzuki, and Stille coupling polymerizations, as compared with the most commonly used homogeneous Pd(PPh3)4. Moreover, this heterogeneous palladium catalyst showed advantage of much less palladium impurity (below 13 ppm) in the isolated polymers. Splet01. jul. 1972 · Pd impurity it stays essentially unchanged. It then narrows down and loses structure and by Ago.2~ Pdo.7~ is roughly Lorentzian, the double hump being completely gone. It is tempting to extrapolate the concentration dependence of the linewi dth at intermediate concentrations linearly to zero on both the Ag and Pd sides. This leads in …
