New 1,3,4-thiadiazole compounds: synthesis, spectroscopic characterisation and theoretical analyses based on DFT calculations
Öz
In this study, four
novel 1,3,4-thiadiazole compounds, derived from α-methyl cinnamic acid, were
synthesised. The structural elucidation was carried out using UV-Vis, FT-IR, 1H-NMR
and 13C-NMR spectroscopy. In addition, the chemical and electronic properties
of the compounds as well as UV-Vis, IR and NMR analyses were theoretically
performed using the density functional theory (DFT). Based on the frontier
molecular orbital (FMO) energies of the compounds, which were obtained from
different methods and basis sets, some chemical reactivity parameters and their
relationship with the methods were analysed. Theoretical calculations were
compared with the experimental results. The electronegative substituents Cl and
NO2 reduced the HOMO–LUMO energy gap (ΔE), and the ones caused a bathochromic
shift in the UV absorption wavelength. The Pearson correlation coefficients
between the experimental and theoretical IR and 13C NMR results were approximately
R = 0.99. It was seen that, the chemical shift of hydrogen bound to an
electronegative nitrogen atom was affected by intarmolecular hydrogen bond
interactions.

Yeni 1,3,4-tiadiazol bileşikleri: sentez, spektroskopik karakterizasyon ve DFT hesaplamalarına dayanan teorik analizler
Öz
Bu çalışmada, α-metil sinnamik asitten türetilen dört yeni
1,3,4-tiadiazol bileşiği sentezlendi. Bileşiklerin yapısal özellikleri UV-Vis,
FT-IR, 1H-NMR ve 13C-NMR spektroskopisi kullanılarak incelendi. Buna ek olarak,
bileşiklerin kimyasal ve elektronik özelliklerinin yanı sıra UV-Vis, IR ve NMR
analizleri teorik olarak yoğunluk fonksiyonel teorisi (DFT) kullanılarak
gerçekleştirildi. Farklı yöntemler ve baz setleri kullanılarak elde edilen,
bileşiklerin sınır moleküler orbital (FMO) enerjilerine dayanılarak, bazı
kimyasal reaksiyon parametreleri ve bunların kullanılan yöntemlerle ilişkisi
analiz edildi. Teorik hesaplamalar deney sonuçları ile karşılaştırıldı.
Elektronegatif Cl ve NO2 sübstitüentlerinin HOMO-LUMO enerji aralığını (ΔE)
düşürdüğü ve UV-absorbsiyon dalga boyunda bir batokromik kaymaya neden olduğu
gözlendi. Deneysel ve teorik IR ve 13C NMR sonuçları arasındaki
Pearson korelasyon katsayıları yaklaşık olarak R = 0.99 olarak hesaplandı.
Elektronegatif azot atomuna bağlı hidrojenin kimyasal kaymasının, molekül içi
hidrojen bağı etkileşimlerinden etkilendiği gözlendi.
