Merritt, Eleanor A.,Malmgren, Joel,Klinke, Felix J.,Olofsson, Berit
, p. 2277 - 2280 (2009)
A range of symmetric and unsymmetric diaryliodonium triflates have been prepared employing urea-hydrogen peroxide as the oxidizing agent. The use of aqueous hydrogen peroxide and catalytic systems with methylrhenium trioxide in the oxidation of iodoarenes
Transition-Metal-Free N-Arylation of Pyrazoles with Diaryliodonium Salts
Gonda, Zsombor,Novák, Zoltán
supporting information, p. 16801 - 16806 (2015/11/16)
A new synthetic method was developed for the N-arylation of pyrazoles using diaryliodonium salts. The transformation does not require any transition-metal catalyst and provides the desired N-arylpyrazoles rapidly under mild reaction condition in the presence of aqueous ammonia solution as a mild base without the use of inert atmosphere. The chemoselectivity of unsymmetric diaryliodonium salts was also explored with large number of examples.
Efficient and general one-pot synthesis of diaryliodonium triflates: Optimization, scope and limitations
Bielawski, Marcin,Zhu, Mingzhao,Olofsson, Berit
, p. 2610 - 2618 (2008/09/19)
Symmetrical and unsymmetrical diaryliodonium triflates have been synthesized from both electron-deficient and electron-rich arenes and aryl iodides with mCPBA and triflic acid. A thorough investigation of the optimization, scope and limitations has resulted in an improved one-pot protocol that is fast, high-yielding, and operationally simple. The reaction has been extended to the direct synthesis of symmetrical iodonium salts from iodine and arenes, conveniently circumventing the need for aryl iodides.
Reaction of iodoarenes with potassium peroxodisulfate/trifluoroacetic acid in the presence of aromatics. Direct preparation of diaryliodonium triflates from iodoarenes
Hossain, Md. Delwar,Kitamura, Tsugio
, p. 6955 - 6960 (2007/10/03)
Diaryliodonium triflates have been directly prepared by reaction of some iodoarenes with aromatic substrates in good yields by using K2S2O8/CF3COOH/CH2Cl2. Treatment of a variety of iodoare
Improved preparation of diaryliodonium triflates
Kitamura,Matsuyuki,Taniguchi
, p. 147 - 148 (2007/10/02)
A reagent prepared from a 1:2 molar ratio of (diacetoxy)iodobenzene [PhI(OAc)2] and trifluoromethanesulfonic acid (TfOH) reacts with aromatic compounds to give diaryliodonium triflates in fairly good yields. The high reactivity and high para se
