TRIS(PENTAFLUOROPHENYL)BORANE

Uses

Tris(pentafluorophenyl)borane (CAS# 1109-15-5) is a useful research chemical, used as a catalyst in the metal-free catalytic reductive cleavage of enol ethers via proposed mechanism of tandem hydrosilylation and silicon-​assisted β-​elimination. Tris(pentafluorophenyl)borane also appears as an ancillary ligand in luminescent isocyano Rh(I) complexes.

Chemical Properties

white powder

Uses

Tris(pentafluorophenyl)borane is used as an excellent activator component in homogeneous Ziegler-Natta chemistry. It is also used as a catalyst for reductions, alkylations, hydrometallation reactions and catalyzed aldol-type reactions. It is a useful Lewis acid and catalyzes hydrosilylation of aldehydes. Further, it is used in olefin polymerization catalysis. It serves as a reagent in the preparation of organometallic complexes. In addition to this, it is useful as polymerization catalysts and used to study the heterolytic cleavage of dihydrogen in associated with tri-tert-butylphosphine.

Uses

Catalyst in organic transformations; cocatalyst with group IV metallocene alkyls in olefin polymerization.

General Description

B(C₆F₅)₃ is a Lewis acid, stronger than the inorganic parent molecule BF₃. In contrast to the prominent Lewis acids, the pentafluorides of the heavier elements of group 15, B(C₆F₅)₃ has no oxidizing properties. B(C₆F₅)₃ forms adducts with neutral and weaker Lewis bases. B(C₆F₅)₃ has the capability to easily accept anionic ligands bonded to metals.
