说明

一般描述

Benzene is a monocyclic aromatic compound used as a solvent in chemical reactions. It is an essential raw material for fuels, rubber and plastics products, detergents, pesticides, and pharmaceuticals.
 

应用

Benzene can be used as a solvent in the:
  • Heck Reaction of vinyl bromides with styrenes to synthesize functionalized 1,3-dienes.
  • Gallium-catalyzed reductive lactonization of γ-keto acids to γ-lactone derivatives.
  • Anionic polymerization of styrene and 1,3-butadiene in the presence of phosphazene as a base.
