4'-TRIFLUOROMETHYLPHENYL ACETYLENE Usage And Synthesis

Chemical Properties

Pale yellow liquid

Uses

4-Ethynyl-α,α,α-trifluorotoluene may be used to synthesize the following:

  • 6,13-bis(4-trifluoromethylphenylethynyl)pentacene
  • 1,2-dialkynylimidazoles
  • trans-[Co(cyclam)(p-CCC6H4CF3)2]OTf complex (where cyclam - 1,4,8,11-tetraazacyclotetradecane; 4-ethynyl-α,α,α-trifluorotoluene - p-CCC6H4CF3; OTf- trifluoromethane sulfonate)
  • 3-spiroazetidinimine-2-oxindoles

General Description

4-Ethynyl-α,α,α-trifluorotoluene reacts with ethanol to afford the corresponding α,β-alkynyl ester. 4-Ethynyl-α,α,α-trifluorotoluene plays the role of a functionalized alkyne in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction on BrPP thin films.
