ABSTRACT:
The present invention relates to an improved method of synthesizing unsymmetric linear organic carbonates comprising the reaction of two symmetric dialkyl carbonates, R.sup.1 and R.sup.2, in the presence of a nucleophilic reagent or an election donating reductant as a catalyst, wherein R.sup.1 and R.sup.2 can be either saturated or unsaturated alkyl or aryl groups, is described. The present invention further provides a preparation method for a nonaqueous organic electrolyte having an unsymmetric linear organic carbonate as a co-solvent.
