Methoxydiethylborane Usage And Synthesis
Chemical PropertiesTransparent to light yellow liquid
UsesReactant involved in:
  • Studying a catalyst for ring-opening metathesis polymerization / vinyl insertion polymerization
  • Reformatsky / quaternary Claisen condensations
  • Enantioselective synthesis of carba-furanose sugars
  • Borane-mediated control radical polymerization for synthesis of fluoropolymers
  • Homologation reactions with sulfonium ylides
  • Trialkylborane promoted adhesion to low surface energy plastics
UsesMethoxydiethylborane is used in analytical studies as a way to identify functional groups in protonated oxygen-containing monofunctional compounds through mass spectrometry.
