Abstract
A process for the preparation of organic cation tetrakis(Faryl) borate salts. The process includes preparation of intermediate, mono-hydrazine substituted (Faryl) compound, from (Faryl) compound using hydrazine at temperatures below 78° C. A stoichiometric excess of hydrazine to the (Faryl) compound to the (Faryl) compound is used. The process further includes the preparation of the organic cation tetrakis(Faryl) borate in ethereal medium.
