Applications
Boron trifluoride-tetrahydrofuran complex is used as a polymerization initiator and as a dopant in the semiconductor industry. It serves as a reagent for deoxofluorination of alcohols and carbonyls. Further, it is used in the synthesis of methacrylate-PEG-methacrylate-boron trifluoride self-doped gel polymer electrolytes and hydroboration-oxidation of divinylferrocene. In addition to this, it is used as a reagent for the preparation of NK1 receptor antagonists, complex polyketide natural products and selective serotonin reuptake inhibitors.

Solubility
Miscible with dimethyl formamide.
