Verwenden
2,3-Dimethyl-1,3-butadiene undergoes Diels Alder cycloaddition reaction and it also participates in polymerization reactions. It is also involved in manufacturing of synthetic rubber.
Allgemeine Beschreibung
2,3-Dimethyl-1,3-butadiene (DMBD) is a conjugated diene. It undergoes Diels Alder cycloaddition reaction with 2-thio-3-chloroacrylamides under thermal, catalytic and microwave conditions. It undergoes thermal [4+2] cycloaddition reaction with 3-acetyl-, 3-carbamoyl and 3-ethoxycarbonylcoumarins under solvent free conditions. DMBD participates in polymerization reactions in the presence of iron dichloride complexes based catalysts.
l?uterung methode
Distil it from NaBH4, and purify it by zone melting. [Beilstein 1 IV 1023.]
