Abstract
U sklopu ovog diplomskog rada pripravljen je 1,2,4,5-tetrafluorjodanilin (itfa) koji je korišten za izučavanje mehanokemijske sinteze trans-1,2-bis(2,3,5,6-tetrafluor-4- jodfenil)diazena (trans-azo) i njegovog cis-izomera pri različitim reakcijskim uvjetima (trajanje mljevenja, vrsta i količina oksidansa, količina pomoćne krutine za mljevenje te vrsta dodane tekućine). Mogućnost nastajanja kokristala pripravljenih azo spojeva, kao donora halogenske veze, izučavana je s odabranim akceptorima halogenske veze, iminima dobivenim kondenzacijom o-vanilina i aromatskih amina, 3-aminoacetofenona (ov3aa) i 4- aminoacetofenona (ov4aa). Mehanokemijska sinteza azo spojeva je praćena visokodjelotvornom tekućinskom kromatografijom, a pripravljeni spojevi izučavani su metodom difrakcije rentgenskog zračenja na praškastom uzorku i razlikovno-pretražnom kalorimetrijom. Metodom difrakcije rentgenskog zračenja na jediničnom kristalu odreĎene su molekulska i kristalna struktura kokristala (ov4aa)2(trans-azo) te dva nusprodukta sinteze spoja itfa: 1,2,4,6,7,9-heksafluor-3,8-dijodfenazina (fzn) i njegovog kokristala (transazo) 2(fzn).
Abstract (english)
Within this diploma thesis, 1,2,4,5-tetrafluoroiodaniline (itfa) was prepared and used to study the mechanochemical synthesis of trans-1,2-bis(2,3,5,6-tetrafluoro-4-iodophenyl)diazene (trans-azo) and its cis-isomer under different reaction conditions (duration of grinding, type and amount of oxidant, amount of auxiliary grinding solid and type of added liquids). The possibility of cocrystal formation of prepared azo compounds as halogen bond donors was studied with selected halogen bond acceptors, imines obtained by condensation of o-vanillin and aromatic amines, 3-aminoacetophenone (ov3aa) and 4-aminoacetophenone (ov4aa). The mechanochemical synthesis of azo compounds was monitored by high performance liquid chromatography, and the prepared compounds were studied by X-ray powder diffraction and differential scanning calorimetry. The molecular and crystal structures of the cocrystal (ov4aa)2(trans-azo) and two byproducts of itfa synthesis 1,2,4,6,7,9-hexafluoro-3,8- diiodphenazine (fzn) and its cocrystal (trans-azo)2(fzn) were determined by single-crystal Xray diffraction.
