, p. 239 - 242 (2009)
An efficient and reusable Cu-exchanged tungstophosphoric acid catalyst is demonstrated for the solvent free hydroarylation and hydroamination reactions of alkynes with numerous arene and amine derivatives, respectively. The catalyst exhibited exceptionally high activity and regioselectivity in both the reactions.

A series of axially chiral biscarboline-based sulfones were synthesized from L-tryptophane and applied for enantioselective 1,2-transfer hydrogenations of ketimines using trichlorosilane. The catalyst 4e, which had a tertiary butyl group, exhibited a good conversion and high enantioselectivities up to 96%ee in the series of reactions.

In this work, a homogeneous organocatalyst was developed for the asymmetric reduction of imines. This catalyst could be separated by cyclodextrin-modified Fe3O4@SiO2 magnetic nanoparticles and then released back into a fre
Palladium-catalyzed aerobic oxidative hydroamination of vinylarenes using anilines: A wacker-type amination pathway
Song, Eunsun,Kim, Hun Young,Oh, Kyungsoo
supporting information, p. 5264 - 5267 (2017/11/06)
A palladium-catalyzed intermolecular hydroamination of vinylarene derivatives using anilines has been developed for the first time under aerobic conditions, where the regioselective formation of N-arylketimines is accomplished. The current aerobic oxidative hydroamination pathway of anilines is distinct from that of palladiumcatalyzed hydroamination reactions that proceed to give sec-arylethylamine and arylethylamine derivatives, identifying a longstanding missing reaction pathway, Wacker-type amination, to N-arylketimines using anilines. The ready availability of both starting materials, vinylarenes and anilines, offers an attractive and facile synthetic route to N-arylketimines in good to excellent yields.
