3,9-DODECADIYNE Usage And Synthesis

Uses

3,9-Dodecadiyne may be used as a monomer to prepare soluble hyperbranched poly(phenylenealkenes) via transition metal-catalyzed polycyclotrimerization. It may also be used as a starting material for preparing 1,2,3,4,9,10-hexaethyl-6,7,8,9-tetrahydroanthracene.

General Description

3,9-Dodecadiyne is an internal diyne that can undergo nickel-catalyzed cycloaddition with aryl nitriles to form pyridines.
