On January 3, 2021, Zhang, Huimiao; Toy, Patrick H. published an article.Quality Control of [2,2′-Bipyridine]-3,3′-diamine The title of the article was Halogen Bond-Catalyzed Friedel-Crafts Reactions of Furans Using a 2,2′-Bipyridine-Based Catalyst. And the article contained the following:
A halogen bond donor based on a 2,2′-bipyridine framework I has been synthesized, and used to catalyze Friedel Crafts reactions of furans II (R = H, Me, t-Bu). Electrophiles used successfully in these reactions included various enones such as 3-buten-2-one, crotonophenone, cyclohexenone, etc.; benzaldehyde, and acetic anhydride. The yields of the reactions were generally good using a moderate catalyst loading (0.025 or 0.1 equivalent) at a relatively low temperature (room temperature or 50°C) in acetonitrile. The catalyst was designed with a biaryl scaffold so that if it indeed proved to be an efficient halogen bond donor organocatalyst, an enantioenriched version of it could potentially serve as a stereoselective catalyst. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Quality Control of [2,2′-Bipyridine]-3,3′-diamine
