Functionalizable salen derivative, 6,6'-(1E
-butyl-4-((trimethylsilyl) ethyn-yl)phenol) (3
), was synthesized by condensation between (1R
) and 3-tert
-butyl-2-hydroxy-5-((trimethylsilyl)ethynyl) benzaldehyde (1
) under refluxing conditions. The title compound was characterized by 1
C-NMR, FT-IR, high-resolution mass spectrometry, optical rotation and melting point determination.
