Point de fusion
Moisture Sensitive
Soluble in hexane, chloroform, dichloromethane, toluene, and polar solvents.


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.


Moisture sensitive. Incompatible with strong oxidizing agents and trimethylaluminum.
