Abstract: An electrolyte for use in a lithium-ion or sodium-ion battery includes a salt such as a lithium salt, a sodium salt, or a mixture of any two or more thereof; and a solvent that includes a compound represented as Formula I, II, or a mixture of any two or more thereof: wherein: R1 is substituted or unsubstituted alkyl, substituted or unsubstituted haloalkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted polyether; R2 is F, a fluoroalkyl, fluorocycloalkyl; R3 is F, a fluoroalkyl, fluorocycloalkyl; and R4 is substituted or unsubstituted alkyl, substituted or unsubstituted haloalkyl, substituted or unsubstituted alkoxy, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted aralkyl, or substituted or unsubstituted polyether; and R5 is a fluoroalkyl or fluorocycloalkyl.

Abstract: Carbonate esters of Formula (I): (R1)(R2)(R3)Si—R4—O—C(═O)—O—R4—Si(R1)(R2)(R3) are prepared by reaction of a silyl-substituted alcohol of Formula (II): (R1)(R2)(R3)Si—R4—OH with an activated carbonyl compound of Formula (III): C(═O)Z2 in the presence of a catalyst (e.g., an bicyclic amidine, a bicyclic guanidine, or a phosphazene) in an aprotic solvent. In Formulas (I) and (II) each of R1 and R2 independently is alkyl; R3 is alkyl or —X1—Si(R5)(R6)(R7); X1 is O or alkylene; R4 is alkylene; and each R5, R6, and R7 independently is alkyl. In Formula (III), Z is 1-N-imidazolyl or 1-N-succinimidyl. In some embodiments, the catalyst used in the methods described herein comprises at least one base selected from the group consisting of a bicyclic amidine and a bicyclic guanidine. The reaction proceeds readily under both bulk and continuous flow reactor conditions.
