Özet:

Green chemistry is a concept in chemistry of increasing significance. Applying fundamental organic syntheses in lieu with the pursuit of an understanding of green chemistry is therefore a challenging and yet prominent necessity. Selective oxidation of primary alcohols to aldehyde derivatives is one of such synthesis in organic chemistry. In this study, 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) radical and a commercially available chlorinated hydantoin containing polymer were used together in the interest of the selective oxidation of primary alcohols. Afterwards, TEMPO attached polymers were designed and synthesized to be facilitated in oxidation reactions. Therefore, the polymer could be easily separated from the reaction media. Each of these polymers was combined with chlorinated hydantoin containing polymers so as to form relatively green and all polymeric reagents. The all polymeric reagents could each time be regenerated and reused in other reactions. Primary alcohols containing different functional groups were utilized to test the performance of the catalyst mixtures. The effect of altered solvent systems was also examined. With all these in mind, an easy and relatively green method was developed for oxidation of alcohols.
