The low temperature solvent-free aerobic oxidation of cyclohexene to cyclohexane diol over highly active Au/Graphite and Au/Graphene catalysts [PDF]

open access: yes, 2018
The selectivity and activity of gold-catalysts supported on graphite and graphene have been compared in the oxidation of cyclohexene. These catalysts were prepared via impregnation and sol immobilisation methods, and tested using solventless and radical ...

Iron Catalysts with Silyl‐NHC Chelate Ligands: Controlling Factors for Hydroboration vs. Dehydrogenative Borylation of Olefins

open access: yesChemistry – An Asian Journal, EarlyView.
Silyl‐NHC chelate iron complexes with various substituents on NHC were synthesized and demonstrated to be active catalysts for hydroboration and dehydrogenative borylation of olefins. The selectivity of these borylation reactions is significantly controlled by the steric bulk of a substituent on the NHC nitrogen.

Stereoselective Synthesis of Cannabidiol and its Unnatural Enantiomer to Evaluate Anxiolytic‐Like Properties and Memory Interactions

open access: yesChemBioChem, EarlyView.
Both (−)‐ and (+)‐cannabidiol (CBD and ent‐CBD, respectively) are synthesized via a highly diastereoselective CSA‐catalyzed Friedel–Crafts reaction. ent‐CBD exhibits anxiolytic‐like effects in aged male mice without impairing long‐term memory formation.
