应用

2-Methylbutane can be used as a reactant to synthesize:
  • Isoprene by two-stage dehydrogenation process using chromia-alumina catalyst.
  • Alkyl aromatic compounds via silver-catalyzed selective C(sp3)–H benzylation reaction in the presence of N-triftosylhydrazones as carbene precursor.

It can also be used as a weakly polar solvent to study the intramolecular charge transfer (ICT) effect and the solvatochromic behavior of the pyrene substituted 1,3,4-oxadiazole derivatives.
