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