General description
4-[(Trimethylsilyl)ethynyl]benzaldehyde can be synthesized by reacting 4-bromobenzaldehyde and triphenylphosphine in anhydrous triethylamine with ethynyltrimethylsilane and then with palladium(II) acetate under argon. It can also be prepared by Sonogashira coupling reaction between 4-bromobenzaldehyde and (trimethylsilyl) ethynyl.
Application
4-[(Trimethylsilyl)ethynyl]benzaldehyde may be used in the preparation of the following:
- 4,4,5,5-tetramethyl-2-{4-[(trimethylsilyl)ethynyl]phenyl}imidazolidine-1,3-diol
- 5,10,15-triphenyl-20-{4-[2-(trimethylsilyl)ethynyl]phenyl}porphyrin
