Trimerik fosfazenin çeşitli mono ve diaminler ile olan reaksiyonlarının incelenmesi

Bu calismada, 4-florbenzaldehitin kuru MeOH ortaminda N-metiletilendiamin ve Nmetil-1,3-propandiamin ile etkilestirilmesinden Shiff bazlari (1 ve 2) elde edildi. Schiffbazlarinin NaBH4 ile indirgenmesinden diaminler hazirlandi (3 ve 4).Hekzaklorosiklotrifosfazenin izopropil amin ile reaksiyonundan mono substitue trimerbilesigi (5) elde edildi. Bu bilesigin NaH ile reaksiyonu sonucunda N,N-spiro kopruluoktaklorobis(siklotrifosfazen) (6) elde edildi. Diaminlerin kuru THF ortaminda koprulubilesik ile nukleofilik substitusyonu sonucunda kismen substitue koprulu bilesikler (8-11) elde edildi. N,N-spiro koprulu oktaklorobis(siklotrifosfazen) (6) ve kismen substituekoprulu fosfazen (8) bilesiklerinin pirolidinin asirisi ile reaksiyonunundan tamamenpiroldin substitue koprulu fosfazen bilesikleri (7ve 12) elde edildi. Elde edilen fosfazenturevlerinin yapilari (5-12) FTIR, MS, 1H, 13C ve 31P NMR teknikleri ile aydinlatildi.Uygun kristali elde edilen (7 ve 10) bilesiklerin kristal yapilari X-isinlari kirinimmetreyontemi ile belirlendi.AbstractIn this study, the Schiff bases (1 and 2) are obtained from the reactions of 4-flourobenzaldehyde with N-methylethylenediamine and N-methyl-1,3-propanediamine,in dry MeOH. The diamines (3 and 4) are prepared by the reduction of Schiff baseswith NaBH4. Mono substituted phosphazene (5) was synthesized by the reaction ofisopropyl amine and hexachlorocyclotriphosphazene. N,N-spiro bridgedoctachlorobiscyclotriphosphazene (6) is obtained from the reaction of NaH andcompound (5). As a consequence of nucleophilic substitution reaction of diamines withN,N-spiro bridged octachlorobiscyclotriphosphazene in dry THF, partially substitutedbridged compounds (8-11) are prepared. The fully pyrrolidine substituted derivatives (7and 12) are prepared by the reaction of the bridged compounds (8 and 6) with theexcess of pyrrolidine. The structures of the compounds have been determined using thedata obtained from FTIR, MS, 1H, 13C ve 31P NMR techniques. The solid-statestructures of 7 and 10 are also determined using X-ray crystallography.
