  A two-step pathway for preparing high pure quaternary phosphonium salts is disclosed. In the first step, hydrogen phosphide (PH 3 ) or a higher phophine reacts with a protonic compound to produce a phosphonium salt, which then reacts with a carbonic acid diester to produce a quaternary phosphonium salt in the second step. On one hand, hydrogen phosphide (PH 3 ) and higher phophines, including primary phosphines, secondary phosphines, and tertiary phosphines, after neutralization with protonic compound, become sufficiently reactive and can be alkylated by carbonic acid diester to form quaternary phosphonium cations. On the other hand, as an anion-exchange procedure is completely avoided, the process not only gives quaternary phosphonium salts of high purity, but also gives people freedom to design the cation and the anion of a quaternary phosphonium salt synchronously by choosing a preferred phosphine and a protonic compound that can supply a desired anion.
