| Hazard Information | Back Directory | [Uses]
2-Ethynylbenzaldehyde may be used in the synthesis of the following:
- iodoisoquinoline-fused benzimidazoles obtained via tandem iodocyclization of 2-ethynylbenzaldehyde with o-benzenediamine and iodine in the presence of copper(I)iodide
- N-[(7,7a-dihydroisoquinolino[2,1-a]perimidin-13-yl)methyl]-N-isopropylpropan-2-amine obtained via a multi-step process
It may also be used in the synthesis of the following substituted 2-alkynylbenzaldehydes by Sonogashira coupling:
- 2-[(2-bromophenyl)ethynyl]benzaldehyde
- 2-[(2-bromo-5-fluorophenyl)ethynyl]benzaldehyde
- 2-[(2-bromo-5-methylphenyl)ethynyl]benzaldehyde
- 2-(phenylethynyl)benzaldehyde
- 2-[(4-methylphenyl)ethynyl]benzaldehyde
