Özet
Bu tez konusu kapsamında salisilik asitin formaldehitle reaksiyonundan yola çıkarak Xabox tipi ligand sentezinde başlangıç maddesi olarak kullanılan 9H-Ksanten-4,5-dikarboksilik asit yapısına denenmemiş ve kısa bir yolla ulaşılmıştır. Fakat reaksiyon mekanizması gereği ksanten ürünü ile birlikte bisfenol A türü ürün oluşumu da gerçekleşmiştir. Reaksiyonlar sonucu ürün karışımı olarak elde edilen fraksiyonlardan biri modifiye Huisgen 1,3 siklokatılma reaksiyonunda katalizör olarak kullanılmış ve olumlu sonuç alınmıştır. Oluşan iki ürününde ayrılması ile yeni ksanten ve bisfenol A tipi ayraca sahip bisoksazolin türevleri elde edilerek onların metal iyonlarına karşı olan ilgileri ve metal kompleksleri ile olan etkileşimleri incelenecektir.
In this research, 9H-xanthene-4,5-dicarboxylic acid structure which is used as starting reagent in Xabox-type ligand synthesis, has been obtained with an untried and shorter method by using the reaction of salycylic acid with formaldehyde. Due to the reaction mechanism, bisphenol A type product was synthesized together with xanthene product. One of the fractions obtained in the mixture was used as a catalyst in modified Huisgen 1,3 cyclo-addition reaction and efficient results have been obtained. With the isolation of both products, bisoxazoline derivatives that have new xanthene and bisphenol-A backbones are going to be obtained and their affinity for metal ions and reactions with metal complexes are going to be investigated.
