Preparation method of 2-ethylanthracene

The invention discloses a preparation method of 2-ethylanthracene. The preparation method comprises the following steps: firstly, 2-(4-ethylbenzoyl) benzoic acid is prepared; then, 2-(4-ethylbenzoyl)benzoic acid is subjected to a reaction with concentrated sulfuric acid in a tubular reactor comprising a T-shaped mixer, a reactor A, a Y-shaped mixer, a reactor B and a separator, and 2-ethyl anthraquinone is prepared; finally, a strong ammonia solution as a reaction medium, crystalline copper sulfate as a catalyst, zinc powder as a reducing agent, and 2-ethyl anthraquinone as a raw material aresubjected to reflux reaction at 70-80 DEG C for 1-3 h, a reaction product is cooled to the room temperature after the reaction and is subjected to silica-gel column chromatography, and 2-ethylanthracene is prepared. The disclosed method is simple to operate, and the yield of the target product is high.

Nickel-Catalyzed Cross-Coupling of Organolithium Reagents with (Hetero)Aryl Electrophiles

Nickel-catalyzed selective cross-coupling of aromatic electrophiles (bromides, chlorides, fluorides and methyl ethers) with organolithium reagents is presented. The use of a commercially available nickel N-heterocyclic carbene (NHC) complex allows the reaction with a variety of (hetero)aryllithium compounds, including those prepared via metal-halogen exchange or direct metallation, whereas a commercially available electron-rich nickel-bisphosphine complex smoothly converts alkyllithium species into the corresponding coupled product. These reactions proceed rapidly (1 h) under mild conditions (room temperature) while avoiding the undesired formation of reduced or homocoupled products.

Nitrous oxide oxidation catalyzed by ruthenium porphyrin complex

Dinitrogen oxide was employed as a clean oxidant for various oxidations in the presence of a catalytic amount of dioxoruthenium tetramesitylporphyrin complex (Ru(tmp)(O)2). A variety of olefins, secondary alcohols, and benzyl alcohols were smoothly oxidized to the corresponding epoxides, ketones, and aldehydes in high yields. In the oxidation of 9,10-dihydroanthracene derivatives, the competitive reactions affording anthraquinones and anthracenes could be regulated by the reaction conditions. At a high temperature (200°C), anthraquinones were selectively produced, while the anthracenes were selectively produced by the addition of sulfuric acid.
