Conclusions 1. For a study of the electronic effects of phosphorus-containing substituants, the rate constants of protophilic isotopic exchange of deuterium in the ortho-, meta-, and para-positions of deuterated phenyl rings of triphenylphosphine, triphenylamine, triphenylphosphine oxide, as well as in the metal- and para-positions of dimethylphenylphosphine, were determined. 2. The rate constants of protophilic isotopic exchange in deuteromethyl groups of diphenyl-m- and diphenyl-p-tolylphosphines, their oxides, and methyldiphenylphosphine were determined. 3. On the basis of the data obtained, it was concluded that trivalent phosphorus has an electron-acceptor character; it is similar to pentavalent phosphorus, and it differs qualitatively from trivalent nitrogen, which is apparently due to the presence of pπ-dπ interaction and the absence of a negligible effect of pπ-conjugation.
