Herein, a ligand-controlled cobalt-catalyzed regiodivergent alkyne hydroalkylation was reported. The sensible selection of bisoxazoline and pyridine-oxazoline ligands led to reliable and predictable protocols that provided (E)-1,2-disubstituted and 1,1-disubstituted alkenes with high E/Z stereoselectivity and regioisomeric ratio starting from identical terminal alkyne and alkyl halide substrates and produced trisubstituted alkenes in the case of internal alkynes. This method exhibited a broad scope for terminal and internal alkynes with a wide range of activated and unactivated alkyl halides and shows excellent functional group compatibility.
Journal of the American Chemical Society published new progress about 18346-57-1. 18346-57-1 belongs to bromides-buliding-blocks, auxiliary class Cobalt, name is Cobalt(II) dibromo(1,2-dimethoxyethane), and the molecular formula is C4H10Br2CoO2, Recommanded Product: Cobalt(II) dibromo(1,2-dimethoxyethane).
