Copper(I)-catalyzed N-arylation (both N1- and N3-) of hydantoins with diaryliodonium salts as aryl partners at room temperature is reported. The transformation allows diverse scopes on both hydantoins and diaryliodonium salts deliver
Copper-catalyzed arylation of polycyclic aromatic hydrocarbons by the PO group

The first example of a directed and regioselective arylation of polycyclic aromatic hydrocarbons (PAHs) by using a PO directing group is reported herein. The protocol uses a cheap copper catalyst, and results in a breakthrough meta-selective C-H functionalization of arylphosphine oxide compounds. Substrates with potential fluorescence properties, for example, pyrene and fluoranthene, were successfully arylated under the system, thus achieving an efficient modification of fluorescent molecules containing the PO functional group.

Paragraph 0045-0046, (2020/07/24)
The invention discloses a benzanthrone derivative and a preparation method thereof. The general formula is shown as a formula I or IV, formula I or IV, R1, R2, R3 is independently selected from hydrogen, halogen, an ester group, an acyl group, a branched-chain or straight-chain C1-C20 alkyl group, a straight-chain or branched-chain C1-C20 alkoxy group, a branched-chain or straight-chain perfluoroC1-C20 alkyl group, a branched-chain or straight-chain perfluoroC1-C20 alkoxy group, a substituted or unsubstituted C4-C40 aryl group, and a substituted or unsubstituted C4-C40 heteroaryl group. The benzanthrone derivative with a novel structure provided by the invention is simple in preparation method, non-toxic and harmless, has yellow fluorescence, can be used as a potential organic functional material, and is an important dye intermediate.
