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.
