Compared with conventional organic solvents, DES have more advantages, such as negligible vapor pressure, non•flammability, good chemical and thermal stability, non•toxicity, biodegradability, recyclability and low price among others. As a new type of solvent, DES has an extremely extensive application prospect. The latest research results of DES is reviewed in this paper. DES as a novel solvent and catalyst was applied in the traditional organic synthesis reaction, mainly including Helogenation reaction, Diels•Alder reaction, Knoevenagel reaction, Henry reaction, Perkin reaction, Paal•Knorr reaction, Biginelli reaction. At last, we hope that DES has a good application prospect in the field of organic synthesis.
