Paragraph 0157-0162, (2021/06/23)
The present invention relates to a metal complex, an organic electroluminescent material, and an organic electroluminescent element comprising the metal complex. The molecular formula of the metal complex is M(LA)x(LB) y(Lc)z, the electroluminescent element containing the metal complex provided by the invention emits green, yellow and red light, has high luminous efficiency and good thermal stability, is easy to prepare and purify, and is an ideal choice as a luminescent material of the organic electroluminescent element.

A safe and scalable synthesis of diaryliodonium triflates was achieved using a practical continuous-flow design. A wide array of electron-rich to electron-deficient arenes could readily be transformed to their respective diaryliodonium salts on a gram scale, with residence times varying from 2 to 60 s (44 examples).

A novel, highly modular synthetic methodology with high functional group tolerance was developed for the construction of iminobenzoxazine derivatives from ortho-cyanoanilides and diaryliodonium triflates via an oxidative arylation-cyclization path. The reaction is supposed to involve the formation of highly active aryl-copper(III) species. In this novel transformation, copper(II) triflate was used as catalyst in 1,2-dichloroethane or ethyl acetate and the reaction takes place at 75 °C in 2-16 h.

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.
Copper-catalyzed oxidative ring closure and carboarylation of 2-ethynylanilides
Sinai, Adam,Meszaros, Adam,Gati, Tamas,Kudar, Veronika,Pallo, Anna,Novak, Zoltan
supporting information, p. 5654 - 5657 (2013/12/04)
A new copper-catalyzed oxidative ring closure of ethynyl anilides with diaryliodonium salts was developed for the highly modular construction of benzoxazines bearing a fully substituted exo double bond. The oxidative transformation includes an unusual 6-exo-dig cyclization step with the formation of C-O and C-C bonds.
Halogen exchange via a halogenation of diaryliodonium salts with cuprous halide

, p. 541 - 548 (2014/01/06)
An efficient halogenation reaction has been developed with diaryliodonium salts and cuprous halides. Various diaryliodonium salts 1 could perform the reaction with readily available CuBr or CuCl in CH3CN at 80°C, assembling bromoarenes or chloroarenes in up to 92% yields. This provides us a method for the transformation from iodoarenes to other haloarenes.
