Synthesis, spectroscopic and molecular structures investigations of some carboxylated schiff bases

A series of nine carboxylated Schiff bases (five of them are newly prepared viz. compounds 5-9), are prepared and characterized by various physico-chemical techniques. The molecular structures of synthesized Schiff bases are investigated by IR, UV-Visible, molar conductivities at different concentrations in two different solvents and by their pH values in ethanolic solutions.The IR spectra show absorptions due to =N⊕H- stretching and -N-H bending vibrations, the UV-Visible spectra indicates absorptions are due to protonated species. The molar conductivities, 0.1-0.6 Ω-1 cm2 mol-1, prove that these compounds are weak electrolytes and are even weaker than tyrosine and phenylalanine, 2.5-13 Ω-1 cm 2 mol-1. The melting points and pH values of Schiff bases are compared with those of some α-aminoacids and some related Schiff bases that have no COOH group in their structures. On the bases of these data, it was concluded that carboxylated Schiff bases exist in two forms, the ionized and the free base where the later is predominant. The ionized form is similar to the zwitterion of the α-aminoacid, in which a proton is transferred from COOH to the azomethine (-CHN-) group.

Water-soluble organocatalysts for hydrazone and oxime formation

The formation of oximes and hydrazones is widely used in chemistry and biology as a molecular conjugation strategy for achieving ligation, attachment, and bioconjugation. However, the relatively slow rate of reaction has hindered its utility. Here, we rep

Synthesis and properties of Schiff bases with nitro group by gas flow crushing

The synthesis of Schiff bases with nitro group had been achieved by low-temperature solid-state reaction using improved gas flow crushing. The structure of the synthesized compound had been characterized by FT-IR, 1H NMR. The optimized geometric structure
