Electrometric behavior of tetraphenylboron (TPB) on mercury electrode was investigated, Potentiometric titration of Hg 2 ++ with TPB − showed that TPB − reacted with Hg 2 ++ with stoichiometric ratios (equivalent) of 1:3 and 1:8 (TPB: Hg 2 ++ ) to form diphenylmercury, Hg(C 6 H 5 ) 2 , and phenylmercuric ion, C 6 H 5 —Hg + . Only 1:3 stoichiometry was found in the reverse titration. Potential response of TPB − on mercury assumed the same result, and furthermore, if the concentration of TPB − was around 10 −3 M or higher, another stoichiometry of 1:1 with formation of Hg(I)‐tetraphenylborate might be possible. Controlled potential oxidation of TPB − on mercury gave Hg(C 6 H 5 ) 2 and C 6 H 5 Hg + which were identified by m. p. measurements and elementary analyses.
