A method for preparing a spiro quaternary ammonium system and electrolytes containing spiro quaternary ammonium cations, comprising a synthesizing step wherein a spiro ammonium system is formed in a medium that can serve as both the reaction solvent and as an electrolyte solvent. A one-solution method of making a non-aqueous electrolyte composition that comprises at least one of a spiro quaternary ammonium compound of the following formula: 

Method for synthesizing quaternary ammonium systems

A method for preparing a spiro quaternary ammonium system and electrolytes containing spiro quaternary ammonium cations, comprising a synthesizing step wherein a spiro ammonium system having a structure of: wherein n is independently an integer from about 0 to about 6;

Provided are methods of purifying quaternary onium salts having the steps of (a) providing an quaternary onium salt solution having a first ionic impurity concentration; (b) providing an ion exchange material charged with electrochemically stable anions; and (c) contacting the salt solution with the ion exchange material to produce an quaternary onium salt solution having a second halide concentration is less than the first ionic impurity concentration.

Method for purifying quaternary onium salts

Provided are methods of producing phosphitylated compounds, including 3'-O-phosphoramidites, comprising the step of reacting a hydroxyl-containing compound with a phosphitylating agent in the presence of a phosphitylation activator selected from the group consisting of: (1) acid-base complexes derived from an amine base of Formula II wherein R, R, R, R, and Rare independently hydrogen, C&#x2013;Calkyl, C&#x2013;Ccycloalkyl, C&#x2013;Caryl, C&#x2013;Caralkyl, C&#x2013;Cheteroalkyl, or C&#x2013;Cheteroaryl, and at least one of R, R, R, R, and Ris not hydrogen; (2) zwitterionic amine complexes; and (3) combinations of two or more thereof, to produce a phosphitylated compound. Further provided are methods for purifying phosphitylated compounds comprising the steps of providing a phosphitylated compound in a solution solvent, contacting said phosphitylated compound with a precipitation solvent, and precipitating said phosphitylated compound.
