Paragraph 0172-0177, (2021/04/03)
The invention provides a fused ring compound containing boron, nitrogen, sulfur atoms and five-membered aromatic heterocycle. The fused ring compound is shown as a formula (I). Compared with the priorart, the fused ring compound containing boron, nitrogen, sulfur atoms and five-membered aromatic heterocycle is adopted as a luminescent material, on one hand, separation of HOMO and LUMO can be achieved through the resonance effect among the boron atoms, the nitrogen atoms and the sulfur atoms, and therefore the small delta EST and TADF effects are achieved, and meanwhile the hybrid fused ring unit has a rigid skeleton structure, the relaxation degree of an excited state structure can be reduced, so that a relatively narrow half-peak width is realized; on the other hand, a five-membered aromatic heterocyclic ring and different substituents can be introduced into the skeleton of the boron/nitrogen/sulfur hybrid fused ring unit, so that the delayed fluorescence lifetime and the half-peak width can be further adjusted.

Under indium Lewis acid catalysis, electron-rich five-membered heteroaryl electrophiles fused with/without a benzene ring were found to couple with amines to produce heteroarylamines with broad structural diversity. The heteroarylamine formation proceeds through the cleavage of a heteroaryl?OMe bond by the nucleophilic attack of the amine based on the nucleophilic aromatic substitution (SNAr) reaction. In contrast to the corresponding traditional SNAr amination, the present SNAr-based heteroaryl amination can be performed without relying on both heteroaryl electrophiles with electron-withdrawing groups and nucleophilicity-enhanced metal amides. High compatibility towards the functional groups such as NO2, Br, I, CF3, CN, CO2Et, pyridyl, thiazolyl, C=C, and OH groups was observed, thus showing the practicality and reliability of this method. Mechanistic studies indicated that a carbon?indium bond is likely to be formed on the heteroaryl ring during the process. (Figure presented.).

The synthesis of di(hetero)arylamines by a transition-metal-free cross-coupling between nitrosoarenes and boronic acids is reported. The procedure is experimentally simple, fast, mild, and scalable and has a wide functional group tolerance, including carbonyls, nitro, halogens, free OH and NH groups. It also permits the synthesis of sterically hindered compounds.

Palladium-catalyzed domino C-H/N-H functionalization for the synthesis of novel nitrogen-bridged thienoacenes and 10H-benzo[4,5]thieno[3,2-b]indole derivatives from dihaloarene is reported. This domino sequence consists of initial C-H functionalization of the benzo[b]thiophene moiety, followed by Buchwald-Hartwig coupling. This transformation is also useful for the synthesis of highly π-extended compounds. Extended heteroacenes: A twofold arylation protocol for the efficient synthesis of 9H-benzo[4,5]thieno[3,2-b]thieno[3,4-d]pyrroles and 10H-benzo[4,5]thieno[3,2-b]indoles was developed (see scheme). The selectivity of this novel sequence allows the construction of highly π-extended heteroacenes.

(Chemical Equation Presented) The Pd-catalyzed amination of a variety of heteroaryl halides has been accomplished by utilizing bulky electron-rich biaryl phosphine ligands. In particular, we report the first couplings of amines with chloro- and bromoindoles bearing a free NH, as well as the first Pd-catalyzed aminations of a 5-halopyrimidine.
Gas-phase cyclisation reactions of 1-(2-arylthiophenyl)alkaniminyl and 2-(aryliminomethyl)thiophenoxyl radicals

Flash vacuum pyrolysis (FVP) of the oxime ethers 12-14 and of the sulfides 18-20 at 650°C (10-2-10-3 Torr) gave products derived from the corresponding iminyl and thiophenoxyl radicals. In all cases, benz[d]isothiazoles (e.g., 26) are formed as major products via SHi mechanisms though the yields are greatest with the iminyl precursors. Alternative pathways observed from the thiophenoxyls in specific cases include the formation of the anilinobenzothiophene 36 and of dibenzothiophene 23, via an SHi process and a spirodienyl rearrangement, respectively. There is no evidence for signicant interconversion of the iminyl and thiophenoxyl species.
