Abstract
Kaynaşık bir heteroksil bileşiği olan yeni epoxyisoquinoline sulfonamide maddesi (I), (4aS,7S,8aR)-8a-bromo-7-methyl-2-tosyl-2,3,4,7,8,8a-hexahydro-1H-4a,7-epoxyisoquinoline, yeşil ve kademeli bir süreç ile sentezlendi. Daha sonra doz hızı of 0.981 kGy/h olan 60Co-gama (?) kaynağı ile oda sıcaklığında 72 saat ışınlandı. I bileşiğinin EPR spektrumları, 150-340 K sıcaklık aralığında X-bant EPR spektrometresi kullanılarak manyetik alanda üç farklı yönelimde kaydedildi. Elde edilen sonuçlara göre, örneğe ait izotropik spektrumların olduğu görüldü ve C ?H_3 H radikalinin varlığı gözlemlendi. Sonuçlar, Bruker WinEPR-Simfonia programı kullanılarak fit edildi. Radikalin aşırı ince yapı sabiti (A) ile deneysel izotropik spektroskopik değeri (g) hesaplandı.
A new epoxyisoquinoline sulfonamide as a fused heterocycle compound (I), (4aS,7S,8aR)-8a-bromo-7-methyl-2-tosyl-2,3,4,7,8,8a-hexahydro-1H-4a,7-epoxyisoquinoline was synthesized using green and cascade progress which was then irradiated by 60Co-gamma (?) ray source with a dose speed of 0.981 kGy/h at the room temperature for 72h. EPR spectra of I compound were measured at different orientations in magnetic field with X-band EPR spectrometer along the temperatures between 150-340 K. Isotropic spectrum was obtained without depending on temperature and radical structure, C ?H_3 H was observed. Radical was simulated using the Bruker software WinEPR-Simfonia and the experimental isotropic g-value with hyperfine coupling constant of radical was calculated.
