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.
Copper-catalyzed oxidative ring closure of ortho-cyanoanilides with hypervalent iodonium salts: Arylation-ring closure approach to iminobenzoxazines

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 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.
