摘要: Tris(pentafluorophenyl)borane is best known for its role as an excellent activator component in homogeneous Ziegler–Natta chemistry. However, the special properties of B(C6F5)3 have made this strong boron Lewis acid increasingly used catalyst or stoichiometric reagent organic and organometallic This includes catalytic hydrometallation reactions, alkylations catalyzed aldol-type reactions. catalyzes tautomerizations can sometimes stabilize less favoured tautomeric forms by adduct formation. It induces some rather unusual reactions early metal acetylide complexes help stabilizing uncommon coordination geometries carbon. The growing number such examples indicates increasing application potential useful aside from established olefin polymerization catalysis.
