Highly nucleophilic Vitamin B12-assisted nickel-catalysed reductive coupling of aryl halides and non-activated alkyl tosylates

Reductive cross-coupling of aryl halides with ubiquitous alkyl tosylates was developed using a combination of nickel and vitamin B12 (VB12: cyanocobalamin) catalysts. The tosylate was activated by reduced VB12 to form alkyl cobalt(iii), which served as a good alkylating agent for aryl-nickel species, leading to C(sp3)-C(sp2) bond formation.

Synthesis of α-Tertiary Amine Derivatives by Intermolecular Hydroamination of Unfunctionalized Alkenes with Sulfamates under Trifluoromethanesulfonic Acid Catalysis

An efficient and mild trifluoromethanesulfonic acid-catalyzed hydroamination of unfunctionalized alkenes to afford α-tertiary amine derivatives at temperatures as low as room temperature is reported. 2,2,2-Trifluoroethyl sulfamate was found to be the optimal nitrogen source because its good solubility in both organic solvents and water facilitated both conversion and purification. The reaction conditions were compatible with a variety of substrate functional groups and afforded moderate to good yields. The desired amine compounds could be obtained easily by means of a mild, one-pot, redox-neutral deprotection procedure. Caryolane amine was synthesized with excellent chemo- and regioselectivities by means of a cascade hydroamination reaction of β-caryophyllene.

Direct cobalt-catalyzed conjugate addition of functionalized aryl halides and triflates: A new strategy for the conjugate addition onto methyl vinyl ketone

An efficient cobalt-catalyzed method for the direct conjugate addition of functionalized aryl halides or triflates onto methyl vinyl ketone is described. The experimentally simple procedure relies on the use of a catalytic system consisting of CoBr2(Bpy) and zinc and does not require the preformation of a stoichiometric organometallic species. The approach described herein displays considerable functional-group compatibility at good to excellent yields. Georg Thieme Verlag Stuttgart.
