Abstract:
An efficient route for the synthesis of novel Schiff bases from the condensation reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with diverse aminophenols in the presence of triethylamine in EtOH at reflux is described. Complexes of transition metals with Schiff base ligand (L) 3c, having the donor atom set N2O2, were studied. The ultraviolet spectral behavior of the complexes in DMSO was investigated and the λ max of these compounds was examined. The structure of the new compounds was confirmed based on their spectral data from IR, 1H NMR and 13C NMR, mass spectra, and elemental analysis.

Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
