Özet
Bu çalışmada, 3 pentanon ve pirol kondenzasyonundan; Meso-dietil-2,2’–dipirometan, benzaldehit ve pirol kondenzasyonundan Meso-fenil-2,2’-dipirometan ve asetofenon ve pirol kondenzasyonundan Meso-fenil-meso-metil-2,2’-dipirometan bileşikleri sentezlenmiştir. Ayrıca bu bileşiklerin seryum amonyum nitrat (CAN) ve FeCl3 varlığında çeşitli konsantrasyonlarda homopolimerleri çalışılmış, reaksiyon şartlarına, oksidant miktarına ve dipirometan yapısına bağlı olarak oligomerler, polimerler ele geçmiştir. Diğer yandan reaksiyon ortamından şartlara bağlı olarak ilgili karbonil bileşiğinin kalikspirolleri ele geçirilmiştir. Bu çalışmayla dipirometanların oksidatif polimerizasyon reaksiyonunun mekanizmasına farklı bir bakış acısı getirilmiş ayrıca öngörülen mekanizmayla oksidasyon reaksiyonu sonucu yüksek verimli ve saf kalikspirol elde edilmiştir.
In this study; Meso-diethyl-2,2’–dipyrromethane from condensation reaction between 3- pentanone and pyrrole, meso-phenyl-2,2’–dipyrromethane from condensation reaction between benzaldehyde and pyrrole, meso-phenyl-meso-methyl-2,2’–dipyrromethane from condensation reaction between acetophenon and pyrrole, were synthesized respectively. Besides they were oxidatively polymerized by CAN and FeCl3. Oligomers and polymers were obtained depending of amount of Ce+4 and dipyrromethane structure. Moreover calixpyrrole of carbonil compound were obtained depending on reaction medium conditions. In this study oxidative polymerization reaction of dipyrromethane was seen from a different diversion, as an addition with the foresighted mechanism as a result of oxidation reaction, pure calixpyrroles were synthesized with high yield.
