Description

  • General description: 2,3-Dimethyl-1,3-butadiene (DMBD) is a conjugated diene.[1] It undergoes Diels Alder cycloaddition reaction with 2-thio-3-chloroacrylamides under thermal, catalytic and microwave conditions.[2] It undergoes thermal [4+2] cycloaddition reaction with 3-acetyl-, 3-carbamoyl and 3-ethoxycarbonylcoumarins under solvent free conditions.[3] DMBD participates in polymerization reactions in the presence of iron dichloride complexes based catalysts.[4]
  • Application: 2,3-Dimethyl-1,3-butadiene was used to investigate the reactions of 1,3-dienes with the Si(001) surface using scanning tunneling microscopy and fourier transform infrared spectroscopy.[5]It may be used in the following processes:Preparation of 1,3,6-triene derivatives of corresponding 1-aryl-substituted 1,3-dienes by 1,4-hydrobutadienylation in the presence of cobalt catalyst.[6]Synthesis of 6-aryl(hetaryl)-3,4-dimethyl-1-nitro-1-cyano-3-cyclohexenes by reacting with gem-cyanonitroethenes.[7]As a halogen trap during the study of the photolysis reaction of dibromo adduct of 2,5-diphenyltellurophene.[8]
