A method for making a vinyl carbonate represented by the formula (I):<paragraph lvl="0"><in-line-formula>CH2=CHOC(O)X1R1 (I)</in-line-formula>wherein X1 is oxygen or sulfur and R1 is a substituted or an unsubstituted aliphatic alkyl, aryl, aryl alkyl, olefinic, vinyl, or cycloaliphatic group comprises: (a) reacting a compound represented by the formula (II):<paragraph lvl="0"><in-line-formula>X2C(O)X1R1 (II)</in-line-formula>wherein X2 is a halogen other than fluorine, with a compound represented by the formula (III):<paragraph lvl="0"><in-line-formula>M1-F (III)</in-line-formula>wherein M1 is selected from a Group IA metal, in the presence of a first phase transfer catalyst and a first organic solvent, to form a compound represented by the formula (IV):<paragraph lvl="0"><in-line-formula>FC(O)X1R1 (IV)</in-line-formula>;and (b) reacting a compound represented by the formula (IV) with a compound represented by the formula (V):<paragraph lvl="0"><in-line-formula>CH2=CHOSi(R2)3 (V)</in-line-formula>wherein R2 is a substituted or an unsubstituted aliphatic alkyl, aryl, aryl alkyl olefinic, vinyl, or cycloaliphatic group, or any combination thereof, in the presence of a metal salt represented by the formula M2-F wherein M2 is a Group IA metal, a second phase transfer catalyst, and a second organic solvent, to form the compound represented by formula (I).
