4'-DIMETHYLAMINOPHENYL ACETYLENE Usage And Synthesis

Uses

4-Ethynyl-N,N-dimethylaniline may be used to synthesize the following:

• copper(I) arylacetylide via reaction with copper(II)acetate
• N,N-dimethyl-4-(3-pyridinylethynyl)aniline via Sonogashira–Hagihara coupling with 3-iodopyridine
• [[5,15-bis[(40-dimethylamino)phenyl]ethynyl]-10,20-bis[(triisopropylsilyl)ethynyl]porphyrinato]magnesium(II) via reaction with dibromo magnesium porphyrin

General Description

4-Ethynyl-N,N-dimethylaniline can be prepared via hydrolysis of 4-(3-methyl-3-hydroxy-1-butynyl)-N,N-dimethylaniline using potassium hydroxide in toluene.
