Diethyl acetylenedicarboxylate is a clear light yellow liquid which has a disagreeable smell. It is a cheap and readily available material in industry. The triple bond is a critical and useful functional group, and it has extensive applications in organic synthesis. It can react with amines, aldehydes, ketones, etc. Therefore it can be used to form various heterocycles.

Synthesis of diethyl acetylenedicarboxylate
Diethyl acetylenedicarboxylate was used in the synthesis of:
- 3,4,5-trisubstituted 2(5H)-furanone derivatives
- highly functionalized thiazolidinone derivatives
- novel cyclic peroxide glucosides
- 4,11-dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction
Diethyl acetylenedicarboxylate is used as a protein cross-linker. It is also used in the synthesis of 3,4,5-trisubstituted 2(5H)-furanone derivatives, highly functionalized thiazolidinone derivatives, novel cyclic peroxide glucosides and 4,11-dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction.
