Triphenylmethylium tetrafluoroborate

Triphenylmethylium tetrafluoroborate (TPTB) is a cationic polymerization agent that can be used to synthesize polymers. TPTB is synthesized by the reaction of diphenyl sulfoxide and triphenylmethyl chloride. The product has been shown to form covalent adducts with various diazonium salts, including phenyldiazonium tetrafluoroborate. TPTB also reacts with carbohydrates and hydroxyl groups to form the corresponding products. The structure of the product is analyzed by x-ray crystallography and gas chromatography-mass spectrometry (GCMS). The carbonyl group in the product can be removed using acidic hydrolysis, which provides additional information about the reaction mechanism.
