Abstract. An imidazolium salt-based hydrogel with hyperbranched topology (hbGel-PEG-TTIm + Br 6 −) was proposed for efficient adsorption towards anionic hexavalent chromium ions (Cr(VI)).For the purpose, a bromo-terminated A 3 type monomer and a imidazole-terminated B 3 type monomer were firstly synthesized via O-esterification and Michael addition, respectively.

Delayed catalyst function enables direct enantioselective ....

Concurrent operation of two or more catalytic cycles requires a delicate balance of relative rates. Zhang et al. developed an amine synthesis in which allenes and nitriles are coupled under reductive conditions. A copper catalyst was charged with successively borylating the allene, coupling the intermediate to the nitrile, and then enantioselectively reducing that next intermediate to the amine.

The Buchwald–Hartwig amination is a chemical reaction used in organic chemistry for the synthesis of carbon–nitrogen bonds via the Palladium-catalyzed coupling reactions of amines with aryl halides. Although Pd-catalyzed C-N couplings were reported as early as 1983, Stephen L. Buchwald and John F. Hartwig have been credited, whose publications between 1994 and the late 2000s established ...
