Description

• General description: Sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, also known as NaBArF, is widely used as a catalyst in the cyclopolymerization of functionalized trienes.[1] NaBArF also acts as a precursor to synthesize other tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (TFPB)-based reagents.[2][3]Sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, also known as NaBAr′4, is a stable and highly soluble compound that has been used as a source of the [BArF] counterion in chemical synthesis. It has been found to be resistant to degradation by various oxidants and highly lipophilic. This compound has been used as a convenient reagent for the generation and stabilization of cationic electrophilic metal alkyl complexes. It has also been used in the living polymerization of ethylene, oligomerization of α-olefins, and olefin hydrogenation and hydrosilylation.
• Application: The TFPB anion can be used to catalyze:In-situ diazo-coupling and N- and C-nitrosations.[4]Synthesis of oxirane from different carbonyl substrates and trimethylsulfonium chloride via phase-transfer catalysis.[5]Synthesis of ion selective membranes[6]9
