| Abstract: | Conclusions Some tetraphenylmethylenediphosphine dioxides, substituted in the methylene bridge, were subjected to potentiometric titration in nitromethane with perchloric acid. The obtained values of the pKa basicity constants (CH3NO2) obey a linear relationship with the  * constants of the substituents.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 199–201, January, 1972. |
