The arylation of N-ethylanilinodiphenylphosphine by bromobenzene in presence of catalytical amounts of nickel(II) affords a mixture of rearranged phosphonium salts from which, p-ethylaminophenyltriphenylphosphonium bromide has been isolated.A phosphasemidine type rearrangement takes place on the N-ethylanilinodiphenylphosphine.The latter, heated in presence of catalytical amounts of nickel(II), is converted to the p-ethylaminophenyldiphenylphosphine and an isomeric ethylaminophenyldiphenylphosphine whose structure is probably ortho.The structural identifications of these two phosphines have been done on the phosphines themselves and on their following derivatives: p-ethylaminophenylmethyldiphenylphosphonium iodide, ethylaminophenyldiphenylphosphine oxides.
