In the last years the interest in organic compounds hypervalent iodine (III) increased significantly due to the fact that there was a rapid development of applications for hypervalent iodine (III) derivatives, in both organic and polymer chemistry. These compounds have a high potential as efficient photoinitiators of cationic polymerization processes. Such a wide range of applications of hypervalent iodine(II) derivatives as diaryliodium salts encourages to search for new synthetic routes and extensive spectroscopic and photochemical developed derivatives. In order to obtain the diaryliodium salt the coupling reactions of [hydroxy(tosyloxy)iodo]arene (HTIA) derivatives with aryl derivatives activated electron electron-withdrawing substituens were carried out. The resulting diaryliodium salt derivatives analyzed with the use of spectroscopic methods including e.g.: NMR spectroscopy and UV-Vis. The diaryliodonium salt was also studied to be used as photoinitiators. To perform this study the research of photolysis was used.
Key wordsdiaryliodonium salts, hypervalent iodine(III) derivatives, cationic photoinitiators, photopolymerization
