설명

애플리케이션

Acetylenedicarboxylic acid is generally used to synthesize its ester derivatives, dimethyl acetylenedicarboxylate (DMAD) and dimethyl acetylenedicarboxylate, which are useful precursors in organic synthesis.
Some of the common applications are listed below:

• Acetylenedicarboxylic acid and its ester derivatives can undergo Cu(I)-catalyzed radical addition with acetophenones to yield furan derivatives.
• It is one of the shortest linear links used in the preparation of Covalent Organic Frameworks (COFs) and Metal Organic Frameworks (MOFs) like IRMOF-0.
• Various hexaarylbenzenes can be built via oxidative cyclodehydrogenation of diaryl alkynes derived from acetylenedicarboxylic acid.
• It can be used as a spacer while synthesizing molecular chains or dendrimers such as 2,3,8-trifunctionalized indenoquinoxaline dendrons and bisarylacetylene chromophores.
