詳細

詳細

2-methylpropene is used to synthesize S-(+)-2,2-Dimethylcyclopropane carboxylic acid via asymmetric cyclopropanation reaction.

アプリケーション

2-Methylpropene can be used in the following reactions:

• Asymmetric synthesis of S-(+)-2,2-dimethylcyclopropane carboxylic acid, a key building block for the synthesis of cilastatin.
• Alkylation of p-xylene to form t-butyl-p-xylene catalyzed by a heteropolyacid.
• Synthesis of poly(2-methylpropene) or polyisobutene.
