Abstract: High surface area macroporous chalcogenide aerogels (chalcogels) MAu2GeS4 (M = Co, Ni) were prepared from K2Au2GeS4 precursor and Co(OAc)2 or NiCl2 by one-pot sol-gel metathesis reactions in aqueous media. The MAu2GeS4-chalcogels were screened for catalytic… read more here.

DOI: 10.1021/acs.organomet.8b00904
Abstract: The intermolecular hydroamination of alkenes with alkylamines has been a long-standing challenge in catalysis, partially due to the near-thermoneutral nature of this transformation. Consistent with this understanding, we report the direct observation of reversible C–N… read more here.

Abstract: The unique property of hexafluoroisopropanol (HFIP) enables the regioselective hydroamination of 1,3-dienes with nitrogen heterocycles in a Markovnikov manner in the presence of catalytic Brønsted acid. This transition-metal-free intermolecular hydroamination protocol is achieved under mild… read more here.

DOI: 10.1021/jacs.9b07253
Abstract: A Ni-catalyzed intermolecular enantioselective hydroamination of branched 1,3-dienes is reported. The method is broadly applicable, highly regio-, chemo- and enantioselective and provides direct access to valuable chiral allylic amines starting from linear or α-branched aliphatic… read more here.
