The method for copper-catalyzed N-arylation of diverse oxadiazolones I (R1 = cyclopropyl, Ph, 5-methylthiophen-2-yl, etc.) by diaryliodonium salts R2I+(R3)R4- (R2 = Ph, 3-(trifluoromethyl)phenyl, 4-nitrophenyl, etc.; R3 = Ph, 2,4,6-trimethoxyphenyl, 4-bromophenyl, etc.) under mild conditions in high yields (up to 92%) using available CuI as a catalyst was reported. The developed method allows utilizing both sym. and unsym. diaryliodonium salts bearing auxiliary groups such as 2,4,6-trimethoxyphenyl (TMP). The steric effects in aryl moieties determined the chemoselectivity of N- and O-arylation of the 1,2,4-oxadiazol-5(4H)-ones I. Mesityl-substituted diaryliodonium salts demonstrated the high potential as a selective arylation reagent. The structural study suggests that steric accessibility of N-atom in 1,2,4-oxadiazol-5(4H)-ones I impacts the arylation with sterically hindered diaryliodonium salts. The synthetic application of proposed method was also demonstrated on selective arylation of 1,3,4-oxadiazol-2(3H)-ones II and 3-(p-Tolyl)-1,2,4-oxadiazole-5-thiol. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Formula: C19H22F3IO3S).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Formula: C19H22F3IO3S
