More than half a century after the discovery of ferrocene structure in 1951, it remains as suitable building block many research areas, including catalysis with development key chiral catalysts. On other hand, gold-mediated has been raised recent years, allowing creation great variety C−C bonds and C-heteroatom bonds. In this context, review covers advances made combination these two iconic fig...
Controlling the activity of an immobilised molecular catalyst by Lewis acidity tuning of the support
The performance profile of a supported metallocene catalyst in slurry-phase ethylene polymerisation can be significantly enhanced by tuning the chemical composition support. By employing supports derived from zinc-containing layered double hydroxides (LDHs), slurry phase productivity (EBI)ZrCl2 (EBI = rac-ethylenebis(indenyl)) quadrupled relative to magnesium-containing Productivity increases a...
