Abstract
The invention relates to a compound represented by the general formula (1), 1 where R1 is an alkyl group or trialkylsilyl group; R2 is an alkyl group, or a combination of R2 and R3 or R4 forms an alkylene group; each of R3 and R4 is a hydrogen or a portion of the alkylene group; and A− is an anion. This compound (an ionic liquid) is useful as a catalyst and/or a reaction solvent in organic syntheses.
