Synthesis, spectroscopic and thermal characterization of non-metal cation (NMC) pentaborates salts containing cations derived from histidine and arginine. Hacettepe Journal of Biology and Chemistry, 40(3), 213-218.1303-5002https://hdl.handle.net/11491/2948researchNovel Schiff base has been synthesized from the reaction of 4,4’-diaminodiphenyl sulfide with 2-hydroxy5-substituebenzaldehyde and 2-hydroxynaphtaldehyde. The compounds were characterized by elemental analysis, FT-IR, 1 H NMR,13C NMR. The UV-visible spectra of the compounds were studied in polar and nonpolar solvents in acidic and basic media. İt is point out that the enol-imine tautomer is dominant only in the solution form the compound 1a-e.4,4’-diaminodifenil sülfit ile 2-hidroksi-5-sübstitüebenzaldehit ve 2-hidroksinaftaldehitin tepkimesi ile yeni Schiff bazları sentezlendi. Bileşiklerin yapıları elementel analiz, FT-IR, 1 H NMR, 13C NMR ile aydınlatıldı. Bileşiklerin polar ve apolar çözücülerdeki asidik ve bazik ortamlardaki UV-vis. spektrumları incelendi. UV-vis. sonuçlarına göre çözücü ortamında enol-imin tautomerinin daha baskın olduğu görüldü.eninfo:eu-repo/semantics/openAccessSchiff BaseDiamine CompoundsBenzaldehydeKeto-Enol TautomerSchiff BazıDaimin BileşikleriBenzaldehitArticle403213218
