The Uses of 4'-Trifluoromethylphenyl acetylene
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.
