We disclose an efficient and practical protocol for the C-H ortho arylation of benzoic acids by using water as an environmentally benign, nontoxic reaction medium. Remarkably, the diaryliodonium salts were first utilized as arylating reagents for C -H arylation of benzoic acids. The choice of water as the solvent is crucial for this reaction, which sets the stage for the broad application of aqueous conditions in C-H functionalization reactions. Overall, this simple catalytic system represents an important complement to previous reports for the preparation of biaryls. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Application of 1204518-02-4).

M.;Cheshko, R. S.. And the article was included in Zhurnal Fizicheskoi Khimii in 1968.Application of 21969-05-1 The following contents are mentioned in the article:

Dipole moments (μH) of 4-XC6H4ZC6H4Y-4′ where Z was CH2, O, S, NH, and CH2CH2 and X and Y were NO2, CN, Cl, Br, I, OH, Me, and NH2 were measured. Values of μH prove existence of the interaction of the substituents in 4,4′ position through bridges with σ and p electrons. Any change in the electron d. at Z in the case of its interaction with substituents of the 1st ring causes a change in degree of its interaction with substituents of the 2nd ring. Only electron effects are transmitted from one substituent to the other substituents of the rings through the bridging groups.
